USS Leonard F. Mason (DD-852) was a Gearing-class destroyer in the United States Navy. She was named for Private First Class Leonard F. Mason USMC (1920–1944), who was posthumously awarded the Medal of Honor for his heroism during the Battle of Guam.

The Gearing class was a series of 98 destroyers built for the U.S. Navy during and shortly after World War II. The Gearing design was a minor modification of the Allen M. Sumner class, whereby the hull was lengthened by 14 ft (4.3 m) at amidships, which resulted in more fuel storage space and increased the operating range.
