Camp Leroy Johnson in New Orleans, Louisiana, was located on the south shore of Lake Pontchartrain in the area bounded west by Franklin Avenue, and east by Inner Harbor Navigation Canal.
In 1947 a formal ceremony was held at the New Orleans Port of Embarkation Personnel Center to rename the base after World War II Medal of Honor recipient Leroy Johnson.
He died on December 15, 1944, near Limon, Leyte, Philippine Islands, shortly after he threw himself on two unexploded Japanese grenades during an assault thus saving two comrades.
Portions of the original property retain military function with the James H. Diamond United States Army Reserve Center located on Leroy Johnson, Drive.
In 1987 portions of the former camp hosted 130,000 people as part of a pastoral visit by Pope John Paul II.
