City (pop., 2000: 390,007), eastern Nebraska, U.S., on the Missouri River, north of its junction with the Platte River.
The city's name, meaning "upstream people," referred to the Omaha Indians. Omaha was founded in 1854 and incorporated as a city in 1857. In 1863 it became the starting point for the Union Pacific Railroad Co.'s first transcontinental railroad and soon grew into a centre of trade and industry. The largest city in the state, it is a major livestock and grain market, as well as a railroad, meat-packing, and insurance centre. It is home to the University of Nebraska and the Joslyn Art Museum.
