Milam County is a county located in the U.S. state of Texas. As of the 2020 census, its population was 24,754. The county seat is Cameron. The county was created in 1834 as a municipality in Mexico and organized as a county in 1837. Milam County is named for Benjamin Rush Milam, an early settler and a soldier in the Texas Revolution.

Benjamin Rush "Ben" Milam was an American colonist of Mexican Texas and a military leader and hero of the Texas Revolution. A native of what is now Kentucky, Milam fought beside American interests during the Mexican War of Independence and later joined the Texians in their own fight for independence, for which he assumed a leadership role. Persuading the weary Texians not to back down during the Siege of Béxar, Milam was killed in action while leading an assault into the city that eventually resulted in the Mexican Army's surrender. Milam County, Texas and the town of Milam are named in his honor, as are many other placenames and civic works throughout Texas.
