Ralston is a city in Douglas County, Nebraska, United States. The population was 5,943 at the 2010 census. Ralston is surrounded on three sides by Omaha, Nebraska but is a separate city. Since Ralston's population is below 10,000, state law technically allows for Omaha to forcibly annex Ralston (as they did with Elkhorn, another nearby city, in 2007, and had previously done with Millard). Omaha officials have never expressed a desire to annex Ralston; an agreement had been signed with Ralston's then-mayor, Wendell Kronberg, in the late 1960s whereby Omaha would leave Ralston alone. Ralston is located at 41128N96214W / 41.20222N 96.03722W / 41.20222; -96.03722 (41.202198, -96.037168). According to the United States Census Bureau, the city has a total area of 1.65 square miles (4.27km2), of which, 1.64 square miles (4.25km2) is land and 0.01 square miles (0.03km2) is water.
