Navy Region Southeast (NAVREGSE or CNRSE) is one of eleven current naval regions responsible to Commander, Navy Installations Command for the operation and management of Naval shore installations in Kansas, Oklahoma, Texas, Missouri, Arkansas, Louisiana, Tennessee, Mississippi, Alabama, Georgia, Florida, and South Carolina. It is headquartered onboard Naval Air Station Jacksonville, in Jacksonville, Duval County, Florida.

CNRSE's motto is "Where the Atlantic Fleet and the Navy's Air Training Command come to train", It gets this motto from the fact that its installations are home to both the Naval Air Training Command located at Naval Air Station Corpus Christi and Naval Education and Training Command, which has its headquarters at Naval Air Station Pensacola. The region's installations also host the United States Navy Flight Exhibition Team, more commonly known as the Blue Angels, which for a brief stint in the late 1940s were under what was then the Naval Air Advanced Training Command.

Most of the current day boundaries of NAVREGSE encompass the former 1903 naval districts of the Sixth, Seventh and Eighth Naval Districts. The Sixth District was headquartered at the Charleston Navy Yard back in the 1900s, while the Seventh District was headquartered at the Naval Air Station Key West (then just a Naval Station) and the Eighth District was located at the Pensacola Navy Yard (now NAS Pensacola). All of these districts were formed in 1903 by then-Acting Secretary of the Navy Charles H. Darling.

However, the linear history of the flag command that is now Commander, Navy Region Southeast are traced through its roots as an aviation-based command, starting as Naval Air Operational Training Command in 1942. The command was then responsible for all aviation-related training in the southeast during World War II. The name then changed to Naval Air Advanced Training Command in the mid-1940s with fighter pilot training as the primary focus, followed by a merger in 1948 with Commander, Fleet Air Jacksonville.

The command then went through a number of name changes between 1974 and 1992, where the flag and mission was changed three times in that span. In 1994, the command became Commander, Naval Base Jacksonville and then finally, on Feb. 2, 1999, became Commander, Navy Region Southeast as part of the navy's eventual formation of its parent command, Navy Installations Command.
