The Holt Lock and Dam is a lock built on the Black Warrior River near Holt, Alabama in Tuscaloosa County. Opening for navigation in 1966, it served as a replacement for a series locks and dams built in the early 20th century.
The lock and dam impounds Holt Lake 19 miles (31 km) upstream to the John Hollis Bankhead Lock and Dam.
