Sarpy County is a county located in the U.S. state of Nebraska. As of the 2020 census, the population was 190,604, and was estimated to be 204,828 in 2024, making it the third-most populous county in Nebraska. The county seat is Papillion and the largest city is Bellevue.

Sarpy County is part of the Omaha-Council Bluffs, NE-IA metropolitan area.

In the Nebraska license plate system, Sarpy County was represented by the prefix "59" (as it had the 59th-largest number of vehicles registered in the state when the license plate system was established in 1922). In 2002, the state discontinued the 1922 system in the three most populous counties: Douglas, Lancaster, and Sarpy Counties. Many license plates issued in Sarpy County featured the stacked format of the 59 code. The county, just south of Omaha, had grown significantly in population in the decades following 1922 and therefore required five characters rather than the four allowed by a standard double-digit county code.
