Arthur Joe Karpus (January 16, 1898 – March 15, 1983) was an American football, basketball and baseball player.

He attended the University of Michigan from 1917 to 1923, winning a total of seven varsity letters, three in basketball, three in baseball and one in football.

[2] His father, Stephen Karpus, emigrated to the United States in 1889 and worked as a sawmill hand in Bay City.

[6] He played at the end and halfback positions for the undefeated 1918 Michigan Wolverines football team that won the Big Ten Conference and national championships.

[9] He also played third base for the undefeated 1919 baseball team that won the Big Ten Conference championship.

[15][16] Despite missing several games, Karpus, playing at the forward position, was the team's high scorer for the second straight year,[17] and he led the team from a last place finish the prior year to a three-way tie for the Big Ten Conference basketball championship.

[18][19] The 1921 basketball team compiled a record of 16–4 and won both games against Michigan Agricultural for the first time in the history of the rivalry.

His performance in the first Illinois game, when he threw nine fouls out of a possible eleven will stand out as one of the most brilliant individual records of the season.

The 1921 Michiganensian noted of Karpus: "When a hit was needed in a pinch, Coach Fisher could usually count on Joe who handled third base in a remarkable fashion.
