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, the team began as an amateur football club in 1890 and was composed primarily of locals before several professional players were added for the 1895 season. 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.
