John Mihalowski (August 12, 1911 – October 29, 1993) was a United States Navy diver and a recipient of America's highest military decoration—the Medal of Honor.

While serving in the Falcon, he played an important role in the rescue of survivors of USS Sailfish (SS-192) and the subsequent salvage of that submarine in 1939.

Following the war, he took part in the harbor clearance in Japan and in salvage efforts during the 1946 Operation Crossroads atomic bomb tests at Bikini Atoll.

He was executive officer of the salvage lifting vessel USS Gypsy (ARS(D)-1) from 1947 to 1948, before transferring to the Fleet Reserve in January 1948.

Chief Torpedoman Mihalowski's official Medal of Honor citation reads: For extraordinary heroism in the line of his profession during the rescue and salvage operations following the sinking of the U.S.S.
