Gulfport Circuit Court is in the Second Circuit District of the Mississippi court system.

At the beginning of World War II, the Naval Construction Battallion Center, the training site for Navy Seebees, was established as an Advanced Base Depot in Gulfport. From the first cooperation between Seabees and the civilian community set the pattern for an association that has since grown into the mutual admiration society. Gulf Coast residents refer to the Seabees as “Our Navy.” At times some 25,000 Naval personnel were stationed at the Center. They lived in wooden barracks, tents and quonset huts. However, the population dropped considerably. With mushrooming commitments for construction forces in Southeast Asia leading the way to an increased mission for the Center in the 1960's the population at the center grew once again.
