USS Ira Jeffery (DE-63/APD-44), a Buckley-class destroyer escort of the United States Navy, was named in honor of Ensign Ira Weil Jeffery (1918–1941) who was killed in action during the Japanese attack on the Hawaiian Islands while serving aboard the battleship California.

The Buckley-class destroyer escorts were 102 destroyer escorts launched in the United States in 1943–44. They served in World War II as convoy escorts and antisubmarine warfare ships. The lead ship was USS Buckley which was launched on 9 January 1943. The ships had General Electric steam turbo-electric transmission. The ships were prefabricated at various factories in the United States, and the units brought together in the shipyards, where they were welded together on the slipways.
