Milam is a census-designated place (CDP) in Sabine County, Texas, United States. It is located along the Sabine River at the junction of Highway 87 and Highway 21. The population was 1,355 at the 2020 census. Milam is the largest city in Sabine County.

With an approximate settling date of 1828, it was originally dubbed Red Mound, but was renamed again in honor of Benjamin Rush Milam (a famous figure in the Texas Revolution) when it became the municipal seat of Sabine County in 1836. Because an increasing number of residents wanted a more central location for the county seat, in 1858 they designated the newly platted town of Hemphill, Texas to fill that role. During the Civil War, the Confederate Army Quartermaster for Sabine County served from Milam.
