Jeff Davis County is a county in the U.S. state of Texas. As of the 2020 census, its population was 1,996.^[1] Its county seat is Fort Davis.^[2] The county is named for Jefferson Davis, who served as the 23rd United States Secretary of War in the 1850s, and as Confederate president.^[3]

Jeff Davis County is recognizable for its unique shape; it is a pentagon that has no north–south nor east–west boundaries, save for a six-mile line serving as its southern boundary. It is the only county in the United States that touches a foreign country (Mexico) at a single point. Jeff Davis is one of the nine counties that compose the Trans-Pecos region of West Texas.

The county contains the 270,000-acre (1,100 km²) Texas Davis Mountains American Viticultural Area. About 50 acres (0.2 km²) are "under vine". The McDonald Observatory, owned by the University of Texas at Austin, is located near Fort Davis.
