Nixa is a city in Christian County, Missouri, United States. As of the 2010 census, the city's population was 19,022. The population was estimated at 22,515 in 2019. It is a principal city, and the second largest city in the Springfield, Missouri Metropolitan Statistical Area.
The area was first settled by farmers who located their farms along the wooded streams near present-day Nixa. The area became a crossroads, as it was a half-day ride with a team of horses from Springfield. Teamsters found it a convenient stopover site when hauling freight between Springfield and Arkansas. The village became known as Faughts. An early resident, Nicholas A. Inman, was a blacksmith from Tennessee, who set up a shop in 1852. When a post office was opened, a town meeting was held to decide on a name for the new community.
