The county is named after Essex, a county in the East of England.

Essex was originally formed as one of four administrative districts within Province of East Jersey in 1675, together with Bergen, Middlesex and Monmouth districts. Essex County was formed within East Jersey on March 7, 1683. The county was named after the English county of Essex. When the provinces of East Jersey and West Jersey were combined in 1702, the county boundaries were retained. Portions of Essex were taken in 1741 and transferred to Somerset County. In 1837, Passaic County was formed from portions of Essex and Bergen counties. In 1857, Union County was created from parts of Essex County.

The municipalities of western Essex County have discussed secession from the county, to create a new county or be annexed to Morris County, spurred mainly by a belief that tax policy benefits the poorer, urban, eastern portions of the county at the expense of the wealthier, more suburban municipalities in the west of the county. From 2001 to 2003, Millburn, Montclair and Roseland all held nonbinding ballot referendums on the issue. Then-Montclair mayor Robert J. Russo gave a statement in 2003 about secession, "I've watched Essex County burden our people, with very little to show for it. We're fiscally conservative here and socially progressive – and we're finally rebelling." • Illustration — Essex Troop, New Jersey National Guard • Illustration — Essex County Hall of Records • Illustration — Thomas Edison Laboratory

According to the U.S. Census Bureau, as of the 2020 Census, the county had a total area of 129.42 sqmi, of which 126.09 sqmi was land (97.4%) and 3.34 sqmi was water (2.6%). The county rises from generally flat in the east to the twin ridges of the Watchung Mountains in the western half, beyond which the land lowers again into the Passaic River valley. The highest elevation is found at four areas scattered between Verona, North Caldwell, and Cedar Grove, reaching 660 ft above sea level. The lowest point is sea level, at Newark Bay.

All of Essex County has a humid subtropical climate (Cfa) if the -3 °C isotherm is used. If the 0 °C isotherm is used, Cfa only exists in eastern Newark and the rest of the county has a hot-summer humid continental climate (Dfa). However temperatures do vary in various locations. In Newark, Eastern Essex County, and Southern/Southeastern Essex County, temperatures are relatively cool to hot, even in the winter months. Western Essex County has similar temperatures to Eastern Essex, but the elevation increase within the Watchung Mountains allows for some minor differences. An example would be that in January on Interstate 280 it could be raining in East Orange. Heading west on 280 there is a large hill that elevates from 150 to, a 500 ft difference. At the top of the hill it could be snowing because of the 3 to 4 degree temperature differences. Newark, New Jersey In recent years, average temperatures in the county seat of Newark have ranged from a low of 24 F in January to a high of 86 F in July, although a record low of -14 F was recorded in February 1934 and a record high of 108 F was recorded on July 22, 2011, which is the highest temperature ever recorded in the state. Average monthly precipitation ranged from 2.99 in in February to 4.76 in in July. In Roseland, average monthly temperatures range from 29.2 F in January to 74.6 F in July.

Based on data from the 2010 census, Essex County is the 14th-most densely populated county in the United States, and was ranked New Jersey's second-most densely populated after Hudson County, which ranked sixth most-densely populated in the nation at 13,731.4 per square mile as of 2010. Newark, with a population density of 11,458.3 people per square mile, is the largest municipality in the county both in terms of land area (24.19 square miles) and population (277,140), while Caldwell is the smallest in terms of land area (1.17 square miles) and Essex Fells has the smallest population (2,113). Many of the county's smallest municipalities have population densities that are comparable to those of many big cities, and are well above the state's average which in turn is the highest in the nation. Like many of the counties of Northern New Jersey near New York City, which tend to have sharp divides between relatively rich suburban neighborhoods and less wealthy, more densely populated cities nearby, the eastern region of Essex County tends to be poorer and more urbanized, while the western parts tend to be more affluent and suburban. The wide area of Eastern Essex has significant pockets of high population, high building density, high poverty, and high crime rates. Within this general area, however, are numerous areas composed of safe, mixed and middle-income neighborhoods of diverse populations. For example, north and west sides of Newark have well-kept suburban areas such as Vailsburg and Forest Hill. The east side of Newark is the Ironbound, a working-class Brazilian and Portuguese community. East Orange is home to the Presidential Estate neighborhood, a well-kept area of large, pre-war, single-family homes. Belleville and Bloomfield are suburbs with historic Italian communities that, in spite of retaining a core Italian-American population, now have many immigrants from Latin America and Asia. As of the 2000 Census, 36% of Nutley residents indicated that they were of Italian ancestry, the 12th-highest of any municipality in the nation and third-highest in New Jersey. Beginning at about the turn of the 20th century, Essex County led the state in the rebuilding and rehab of its housing stock. In the 2000s, Newark led the state in the issuance of building permits. Many reasons were cited: citywide incentives to encourage construction development, an improving local economy, the rising demand of low-cost housing so close to Manhattan. Newark has since then become one of the fastest-growing cities in the entire Northeast, and reported a gain in median income and drop in poverty rate. This is a turnaround from the deterioration and abandonment experienced in the post-riot 1970s, 1980s and early part of the 1990s. Crime in this part of the county has traditionally been among the highest in the state and the country as well, but recently has also seen significant declines, mirroring its large neighbor to the east, New York City. By 2006, crime in Newark had fallen 60% over the previous decade to its lowest levels in 40 years. Neighboring East Orange has also experienced a decline in crimes, dropping 50% in the three years (2005 to 2007). While crime rates have fallen significantly in these cities in recent years, they nonetheless remain high here compared to national crime statistics, as well as Irvington, and Orange. In 2008, Newark had 67 homicides, down from 105 in 2007 and the record of 161 murders set in 1981. In contrast, Western Essex tends to be more suburban and affluent. Within this region are some of the most diverse and racially integrated municipalities in the state and nation, including Montclair, West Orange, South Orange and Maplewood. Many of these municipalities are well-known magnets for people moving from New York City, such as Glen Ridge, Montclair, Verona, Cedar Grove, South Orange and West Orange. The communities of Livingston, West Caldwell, South Orange, Maplewood, Millburn, North Caldwell, and Essex Fells are some of the wealthiest towns in the county. Short Hills (in Millburn), South Orange, West Orange, and Livingston have large Jewish communities. Short Hills has a popular upscale shopping mall, The Mall at Short Hills located near affluent communities in Morris and Union counties. As the poorest place in the county, Newark has a median household income of $33,025 and a per capita income of $17,198; at the other extreme, Essex Fells, one of the wealthier places in the county and the 4th wealthiest municipality in the state, has a median household income of $174,432 and a per capita income of $89,316.

As of the 2020 census, the county had a population of 863,728 and a median age of 37.1 years. 23.4% of residents were under the age of 18 and 13.3% were 65 years of age or older. For every 100 females there were 92.6 males, and for every 100 females age 18 and over there were 89.5 males age 18 and over. The racial makeup of the county was 30.3% White, 38.8% Black or African American, 0.5% American Indian and Alaska Native, 5.5% Asian, Note: the US Census treats Hispanic/Latino as an ethnic category. This table excludes Latinos from the racial categories and assigns them to a separate category.

Essex County is traversed by a number of highways. Three primary interstates and one auxiliary cross the county. This includes two long distance main interstates, one north–south Interstate 95 (concurrent with the New Jersey Turnpike toll road) and one east–west Interstate 80. East-West Interstate 78 also crosses the county. All of these only have interchanges in one municipality in the county, Newark for I-95 and I-78 and Fairfield for I-80. Interstate 280 passes through the county in a northeast–southwest direction and has exits in Roseland, Livingston, West Orange, Orange, East Orange and Newark, making it one of the most important roads for intracounty travel. Essex County also has four U.S. Routes that cross it. Route 1/9 are concurrent and a freeway throughout their length in the county. They pass through Newark from Elizabeth in Union County to Kearny in Hudson County. It crosses over the Passaic River on the Pulaski Skyway, which bans trucks, so just before it leaves the county in the north Truck 1/9 splits for the traffic that is not allowed on the bridge. Truck 1/9 is also a freeway its entire length in the county. U.S. Route 22 eastern terminus is in Newark the only municipality it crosses in the county. It is a freeway along it route in Essex County. It connects Newark with points to the east. The last U.S. Route in the county is U.S. Route 46, which passes through Fairfield, where it is a major commercial road that parallels Interstate 80. The most important state road in the county is the Garden State Parkway which passes north–south through the county, connecting Union Township in the south in Union County to Clifton in the north in Passaic County. It is a toll road, a freeway, and bans trucks of more than 7,000 pounds during its entire length in the county. It has one interchange in Irvington, one in Newark, two in East Orange, and four in Bloomfield. Outside the county, it is the longest road of any kind in the state. New Jersey Route 7 is a major arterial road in Nutley and Belleville. It has two discontinuous sections. The southern section starts at an overpass for Route 21 and passes over the Belleville Turnpike Bridge into border between Hudson and Bergen counties.

There are many buses that operate around the county, with NJ Transit (NJT) headquarters located just behind Newark Penn Station, a transit hub in the eastern part of the county. There are two major bus terminals in the county, Newark Penn Station and the Irvington Bus Terminal. Community Coach, and OurBus operate buses from Essex County to the Port Authority Bus Terminal in New York City. Some of the NJ Transit bus lines follow former streetcar lines.

Essex County has a large rail network, but most train service is geared toward the heavily utilized Newark/New York City commute. All of the passenger rail lines in the county are electrified, although many trains that continue on to non-electrified lines use dual-mode or diesel push-pull locomotives.

NJ Transit has five lines that make stops in the county. All of them stop at either Newark Penn Station or Newark Broad Street station. The Northeast Corridor Line from Trenton with connections from Philadelphia's 30th Street Station, Camden, and Princeton has stops at Newark Airport and Newark Penn Stations before continuing to Secaucus Junction and New York Penn Station. The North Jersey Coast Line from Bay Head or Long Branch also stops at Newark Airport and Newark Penn Stations before continuing to Secaucus Junction and New York Penn Station or Hoboken Terminal. The Raritan Valley Line from High Bridge usually terminates in Newark Penn Station, but mid-day trains continue to New York and one eastbound morning train terminates at Hoboken Terminal. The Montclair-Boonton Line from Hackettstown or Little Falls has six stations in Montclair, one in Glen Ridge, and two in Bloomfield before reaching Newark Broad Street Station and continuing to Secaucus Junction and New York Penn Station or Hoboken Terminal. The Morris and Essex Lines from Hackettstown and Peapack-Gladstone has two stops in Millburn, one in Maplewood, and two each in South Orange, Orange and East Orange before reaching Newark Broad Street and continuing to Secaucus Junction and New York Penn Station or Hoboken Terminal.

• Illustration — Broad Street station of Newark Light Rail The Newark Light Rail is completely contained within the county. It has 17 stations in Newark, Belleville, and Bloomfield and also operates out of Newark Penn Station. It is composed of two lines: the Newark City Subway and the Broad Street Extension. The Newark City Subway is the only survivor of the many street car lines that once crossed New Jersey, although it no longer uses street cars. It survived in part because it does not include street running, instead following the abandoned Morris Canal right of way before going underground. It has one station in Bloomfield and one in Belleville on the old Orange Branch of the New York & Greenwood Lake Service of the Erie Railroad before entering Newark and turning onto the Morris Canal right of way. From there it follows Branch Brook Park before turning into downtown Newark as a subway. It has nine stops in Newark before terminating in Newark Penn Station. The Broad Street Extension was built to provide connections between Newark Penn Station and Newark Broad Street Station and service to the waterfront of Newark. Leaving Penn Station, the line comes up from the subway and runs on streets or at grade for most of its length. It stops at NJPAC/Center Street, Atlantic Street, and Riverfront Stadium before reaching Broad Street Station. From Broad Street it takes a different route stopping at Washington Park and NJPAC/Center Street before arriving at Penn Station.

The PATH also operates out of New York Penn Station. It has direct service to Harrison, Jersey City, and Lower Manhattan. With a free transfer, the PATH also provides service to Hoboken, as well as Greenwich Village, Chelsea, and Midtown Manhattan.

Amtrak has two stations in the county, Newark Penn Station and Newark Airport, both on the Northeast Corridor. Newark Penn Station has service on the only high speed train in the Western Hemisphere, the Acela Express, to Boston, Philadelphia, Baltimore, and Washington, D.C.
