The 1st Tennessee Infantry Regiment was an infantry regiment that served in the Union Army during the American Civil War. Recruited from Tennessee Unionists, the regiment was organized in August 1861 and fought at Mill Springs in January 1862. The unit served in Sanders' Knoxville Raid, at Bean's Station, and Mossy Creek in 1863 as a mounted infantry unit. The regiment was dismounted and fought in the Atlanta campaign until it was withdrawn in August 1864. Subsequently, it performed garrison duty in East Tennessee until August 1865.
