• Illustration — The Vicente Martínez Adobe, built in 1849 by a son of Ygnacio Martínez, is the oldest building in Martinez. • Illustration — The John Muir National Historic Site, home of famed naturalist John Muir from 1880 until his death in 1914 The lush Alhambra Valley is believed to have been a seasonal “pantry” used for foraging by the local population of the Karkines Indians. The Karkines are a part of the Ohlone (Costanoan) Indian group. In 1824, the western side of Martinez, Alhambra Valley was included in the Rancho El Pinole Mexican land grant to Ygnacio Martínez. East of these lands was the Rancho Las Juntas, a grant made to Irish born William Welch in 1844; his land lay between the lands of Martinez and Pacheco. In 1847, Dr. Robert Semple contracted to provide ferry service from Martinez to Benicia, which for many years was the only crossing on the Carquinez Strait. By 1849, Martínez served as a way station for the California Gold Rush. The town was laid out in 1849 by Col. William M. Smith and named for Martinez. It became the county seat in 1850, but could not incorporate at the time because it lacked the 200 registered voters required, and would not become a city until 1876. Martinez was the home of naturalist John Muir from 1880 until his death in 1914. He was buried about a mile south of the building that is now the John Muir National Historic Site. Also nearby is the Vicente Martinez Adobe, built in 1849 by the son of Ygnacio Martinez. The first post office opened in 1851. In 1860, Martinez played a role in the Pony Express, where riders would take the ferry from Benicia (particularly if they missed the steamer in Sacramento). The first oil refinery in the Martinez area was built in 1904 at Bull's Head Point, a then-unincorporated waterfront area two miles east of the downtown district. That area soon became known as Mococo, following the 1905 arrival of a smelting works, operated by the Mountain Copper Company (Mo Co Co). • Illustration — The historic Contra Costa County Courthouse was built in 1901. That first facility, operated by the Bull's Head Oil Company, was followed in 1908 by a test refinery built by the Pacific Coast Oil Company. Shortly thereafter, Pacific Coast became part of Standard Oil (now Chevron), and consolidated their oil refining operations in the Point Richmond, Hercules, Rodeo waterfront corridor some 12 mi to the west of Martinez. In 1913, the Golden Eagle facility became the third oil refinery to be built in the area. It was located in the newly created company town of Avon, immediately to the East of Martinez. A fourth refinery, built by the Shell Oil Company on land adjacent to the Martinez City limits, went online in January 1916. The Shell Oil refining facility is still operational today (Currently owned by PBF Energy), maintaining the city's position as a significant petroleum processing center. The Golden Eagle Refinery (currently owned by Marathon Petroleum Company) was idled in April 2020 as a response to lower petroleum demand during the COVID-19 pandemic. Folk etymology in Martinez claims the invention of the Martini cocktail and that it is named for the city.

• Illustration — The Benicia-Martinez Bridge, which crosses the Carquinez Strait, connects Martinez in the south to Benicia in the north (top). According to the United States Census Bureau, the city has a total area of 13.6 sqmi, of which 1.0 sqmi (7.36 percent) is covered by water. The city is largely surrounded by water and regional open-space preserves. The Martinez–Benicia Bridge carries Highway 680 across the eastern end of the Carquinez Strait to Solano County. The city is a densely built downtown valley threaded by Alhambra Creek and north of Highway 4. Suburban areas stretch south of Highway 4 to join the neighboring city of Pleasant Hill. Unincorporated areas include the rural Alhambra Valley and the Franklin Canyon area. The Martinez Regional Shoreline bounds the city to the north along the Carquinez Strait. Carquinez Strait Regional Shoreline includes the Franklin Hills west of downtown, stretching west to the unincorporated community of Port Costa and the town of Crockett. Briones Regional Park borders the Alhambra Valley to the south. Waterbird Regional Preserve and the McNabney Marsh border the city and Highway 680 to the east. Martinez's location at the east end of the Carquinez Strait as it widens to Suisun Bay includes dramatic water views stretching to the Sierra range. Views from surrounding ridge tops stretch to nearby Mount Diablo, Mount Saint Helena, Mount Tamalpais, and others. • Illustration — Aerial view of Martinez (bottom); Benicia is located across the Carquinez Strait (top). Martinez is one of the only two places in the Bay Area, the other being Golden Gate Bridge, where the Bay Area Ridge Trail and the San Francisco Bay Trail converge. The Bay Trail is a planned recreational corridor that, when complete, will encircle San Francisco and San Pablo bays with a continuous 400 mi network of bicycling and hiking trails. It will connect the shoreline of all nine Bay Area counties, link 47 cities, and cross the major toll bridges in the region, including the Benicia–Martinez Bridge. To date, approximately 240 mi of the alignment—over half the Bay Trail's ultimate length—have been completed. The Bay Area Ridge Trail ultimately will be a 500+ mile trail encircling the San Francisco Bay along the ridge tops, open to hikers, equestrians, mountain bicyclists, and outdoor enthusiasts of all types. So far, over 300 mi of trail have been dedicated for use. East Bay Regional Park District's Iron Horse Regional Trail will join the Bay Trail along the waterfront, and the Contra Costa Canal Trail threads through the city from Pleasant Hill to the south.

Martinez has a mild Mediterranean climate (Köppen climate classification: Csa/b). Summers are warm and dry, with some morning fog during sea breezes. The maritime influence is much less significant than in other parts of the Bay Area that are closer to the Pacific, which causes very high daytime averages compared to San Francisco and Oakland in summer. However, nights normally cool off significantly, which results in daytime highs around 87 F and nighttime lows of 55 F during July and August. Winters are wet and cool with occasional frost. The majority of the city is within a USDA hardiness zone of 9b.
