1941–42 Oshkosh All-Stars season

The 1941–42 Oshkosh All-Stars season was the All-Stars' fourth year in the United States' National Basketball League (NBL), which was also the fourth year the league existed. Seven teams competed in the NBL in 1941–42 and the league did not use divisions.

The All-Stars played their home games at South Park School Gymnasium. For the fifth consecutive season, the All-Stars finished the season with either a division or league best record (20–4). They then went on to win their second consecutive league championship by defeating the Fort Wayne Zollner Pistons, two games to one in a best-of-three series.

Head coach Lon Darling won the league's Coach of the Year Award. Players Leroy Edwards and Charley Shipp earned First Team All-NBL honors for the second straight season.
