Trigg County is a county located on the far southwest border of the U.S. state of Kentucky. As of the 2020 census, the population was 14,061. Its county seat is Cadiz. Formed in 1820, the county was named for Stephen Trigg, an officer in the American Revolutionary War who was killed at the Battle of Blue Licks, now in Robertson County, Kentucky. It was a victory for British and allied troops.

Following the Prohibition era, Trigg continued as a prohibition or dry county until 2009. That year the county's voters narrowly approved a referendum to repeal the prohibition on alcohol sales for off-premises consumption.

Trigg County is part of the Clarksville, TN–KY Metropolitan Statistical Area.
