Oakley George Kelly (December 3, 1891 – June 5, 1966) was a record setting pilot for the United States Army Air Service.

He was born on December 3, 1891, in Geneva, Pennsylvania and grew up in Grove City.

In May 1922, Lieutenant Oakley G. Kelly and Lieutenant John Arthur Macready were awarded the 1922 Mackay Trophy for the beating the world's air endurance record and staying aloft for 36 hours, 4 minutes, and 32 seconds.

[1] On May 2, 1923, Lieutenants Kelly and Macready departed in their single-engined, high-wing Army Fokker T-2 from 2,625 miles (4,225 km) from Mitchel Field, New York, and landed in San Diego, California, on May 3 after a flight of 26 hours, 50 minutes and 383⁄5 seconds,[2] setting the record for transcontinental flight by a heavier-than-air craft[3] winning the 1923 Mackay Trophy.

In October 1924, Kelly piloted Ezra Meeker along portions of the Oregon Trail to generate support for marking and preserving the historic route using a de Havilland DH.4 biplane.
