William "Bill" Franklin Porter III (March 24, 1926 – March 10, 2000) was an American track and field athlete, gold medal winner of the 110-meter hurdles at the 1948 Summer Olympics.

[2][1] Porter won his only AAU Championship title in 1948 in 110 m hurdles[3] and thus qualified for the Olympic Games.

He beat Porter to the second place at the 1947 and 1948 NCAA Championships,[2] but fell ill at the 1948 Olympic trials and did not qualify.

In the finish, Porter gained a clear win, setting his personal best and a new Olympic record.

He later worked for the Northwestern Alumni Association Board and after that opened a medical supply agency in California.
