• Illustration — The Harper House The original portion of what is now known as Rock Island was called Farnhamsburg – after the original two homes were built by Colonel George Davenport and Russell Farnham in 1826. Davenport and Farnham were business partners, trading with the local Native Americans. The original city plat was filed on July 10, 1835, and was named Stephenson. It was renamed Rock Island in March 1841. The southern portion of Rock Island, including today's Watch Hill area, was originally known as Searstown. It was named after David B. Sears, who built the Sears Power Dam on the Rock River. Searstown was annexed by Rock Island in 1915. The Chicago, Rock Island & Pacific Railroad (RI) was founded here in 1851, known informally as the Rock Island Line; over the next century, the railroad grew to serve fourteen states but ended in bankruptcy in 1980. As part of later nineteenth-century development, two first-class hotels: the Harper House (built by Ben Harper and opened in February 1871) and the Rock Island House were built in town. The Rock Island Arsenal has manufactured military equipment and ordnance for the U.S. Army since the 1880s. The Rock Island Southern Railway was an interurban line that ran from Rock Island to Monmouth, Illinois, then onward to Galesburg, Illinois. It was built between 1906 and 1910. A portion of the trackage, from Rock Island to Preemption, Illinois, was shared with the CRI&P line that served the coal mines in Cable, Illinois, and Sherrard, Illinois. The line finally folded in 1952. Construction began in April 2017 for a new Rock Island County courthouse. The $28 million project was completed in the fall of 2018, and the old courthouse was expected to be torn down upon completion of the new building. Resident opposition temporarily delayed the demolition, but the building was demolished in April 2023.

According to the 2010 census, Rock Island has a total area of 17.872 sqmi, of which 16.85 sqmi (or 94.28%) is land and 1.022 sqmi (5.72%) is water.

The first football game in what was to become the National Football League was played at Rock Island's Douglas Park in September 1920. It was hosted by the Rock Island Independents (1907–1926), who were a charter NFL franchise in 1920. The Rock Island Islanders were a minor league baseball team that played for 37 seasons between 1901 and 1948. The Islanders played at Douglas Park and were affiliates of the Cincinnati Reds and Philadelphia A's. Karters flock to Rock Island every year for the prestigious "Rock Island Grand Prix" on Labor Day weekend, which attracts competitors from across the United States and the world. With exception to 1997, when the annual race was canceled due to legal liability issues, the Rock Island Grand Prix has been held every year since 1994.

Rock Island was also the longtime former home of WHBF-TV's former sister radio stations, WHBF and WHBF-FM, although it does remain the licensed city of those stations. National Public Radio member station WVIK is licensed to and located in Rock Island on the campus of Augustana College, and WGVV-LP, which is also licensed to the city of Rock Island.

• Illustration — The Rock Island Line shipped goods from west of the Mississippi to Chicago. This map shows the railroad's extent in 1965. Quad Cities MetroLINK provides bus service on numerous routes connecting Rock Island to destinations across the Quad Cities. District Station in downtown Rock Island serves as a hub of the system. The first railroad bridge across the Mississippi River was built between Arsenal Island and Davenport in 1856. Many steamboat pilots felt that the bridge had been intentionally positioned to make it hard for them to navigate, and this conflict reflected a larger rivalry: St. Louis-based steamboat transit against Chicago-based railroad transit. Two weeks after the bridge opened, the steamboat Effie Afton collided with the bridge, caught fire, and damaged the bridge. The owner of the Effie Afton sued the bridge company for damages, and the case, Hurd v. Rock Island Bridge Co., featured Abraham Lincoln as one of the lawyers who defended the railroad at trial in September 1857. This test case was appealed to the United States Supreme Court, which ruled in favor of the railroad in 1862. Although the original bridge is long gone, having been replaced in 1866 with a heavier bridge, a monument exists on Arsenal Island marking the Illinois side. On the Iowa side, the bridge was located near where 4th and Federal streets intersect with River Drive. The Lock and Dam No. 15 and the Government Bridge are located just southwest of the site of the first bridge. The Government Bridge, completed in 1896, is notable for having two sets of railroad tracks above the car lanes. There are only two bridges in the world with this feature. Three other bridges span the river between Rock Island and Davenport. The Crescent Rail Bridge is a railroad-only bridge, completed in 1899. The Centennial Bridge was completed in 1940 for autos only. The newest bridge is the Interstate 280 bridge, completed in 1973. Lock and Dam No. 15, completed in 1934 as a federal Works Progress Administration (WPA) project during the Great Depression, is the largest roller dam in the world. On the south side of the city, overlooked by the Black Hawk State Historic Site, are auto and railroad crossings of the Rock River to Milan, Illinois. This set of bridges also crosses the historic Hennepin Canal and Sears Dam (this was named after the entrepreneur David B. Sears, who previously built the Sears Dam between Arsenal Island and Moline.) In 2007 a new bridge was completed between 3rd Street Moline/southeast Rock Island and Milan.
