Kenedy County is a county located in the U.S. state of Texas. As of the 2010 census, its population was 416.Its seat is Sarita. Kenedy County has the distinction of having the fourth-lowest population of any county in the United States, following Loving County, Texas, Kalawao County, Hawaii, and King County, Texas. It is also the easternmost and southernmost county in the United States that has more square miles than people.
The county was created in 1921 from parts of Hidalgo and Willacy counties and is named for Mifflin Kenedy, an early rancher in the area. In 1999, Hurricane Bret struck the county, but damage was minimal due to the county's low population. The Peñascal Wind Power Project was built near Sarita in the early 21st Century and is expected to slightly raise the population of the area.
Kenedy County is included in the Kingsville Micropolitan Statistical Area.
