The Diocese of St. Augustine (Latin: Dioecesis Sancti Augustini) is a Latin Church ecclesiastical territory of the Catholic Church, located in the northeastern section of Florida in the United States. It includes the cities of St. Augustine, Jacksonville, and Gainesville.

The Diocese of St. Augustine is a suffragan diocese in the Ecclesiastical Province of Miami, covering much of North Florida. The bishop's seat is the Cathedral Basilica of St. Augustine. As of 2023, the current bishop is Erik T. Pohlmeier.

On March 11, 1870, the Vatican erected the Diocese of St. Augustine. It covered most of the Florida peninsula until the 1950s, when Florida's expanding population necessitated the creation of new dioceses (until 1958 it was the only Catholic See in Florida).
