The Greensburg Athletic Association was an early organized football team, based in Greensburg, Pennsylvania, that played in the unofficial Western Pennsylvania Professional Football Circuit from 1890 until 1900. At times referred to as the Greensburg Athletic Club...

...In 1894 it was discovered that the team had secretly paid formerly Indiana Normal (now Indiana University of Pennsylvania) player, Lawson Fiscus, to play football and retained his services on salary. The team was the chief rival of another early professional football team, the Latrobe Athletic Association.

Aside from Fiscus, the Greensburg Athletic Association included several of the era's top players, such as: Charlie Atherton, George Barclay, Ross Fiscus, Jack Gass, Arthur McFarland, Charles Rinehart, Isaac Seneca and Adam Martin Wyant. Charlie Atherton is credited with inventing the place kick,^[1] and George Barclay invented the first-ever football helmet.^[2][3] The team's home games were played at Athletic Park (which was later renamed Offutt Field).
