Frank Farmer Loomis Jr. (August 22, 1896 – April 4, 1971) was an American athlete, winner of 400 m hurdles at the 1920 Summer Olympics in Antwerp.

[1] His brother, Jo Gilbert Loomis, was a substitute sprinter at the same Olympics.

Although Loomis was an AAU champion in 220 yd (200 m) hurdles in 1917 and 1918 and in 440 yd (400 m) hurdles in 1920, the main favorite in Antwerp was John Norton, who had run a new world record of 54.2 just two months before the Olympics.

[2][3] Landers-Loomis Field in Oregon, Illinois, is named partially in his honor.
