The 1955 PGA Championship was the 37th PGA Championship, held July 20–26 at Meadowbrook Country Club in Northville Township, Michigan, northwest of nearby Detroit. Doug Ford won the match play championship, 4 & 3 over Cary Middlecoff in the Tuesday final; the winner's share was $5,000 and the runner-up's was $3,000.
Ford was also the medalist in the stroke-play qualifying with a 135 (−7); he was the last medalist as the format was changed in 1956 to seven rounds without a qualifier for two years, then to 72-hole stroke play in 1958.
This was the first of two major titles for Ford, who also won the Masters in 1957.
Defending champion Chick Harbert was defeated in the second round by Johnny Palmer, 1 up. No former champion advanced past the second round.
This was second time in three years the PGA Championship was played near Detroit; the 1953 event was played at Birmingham Country Club in Birmingham, about 20 miles (30 km) northeast.
