The 1940–41 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 1940–41, and for the first time the league did not use divisions.
The All-Stars played their home games at South Park School Gymnasium. For the fourth consecutive season, the All-Stars finished the season with either a division or league best record (18–6). They then went on to win their first league championship after having lost in the finals the previous three seasons.
Head coach George Hotchkiss won the league's Coach of the Year Award. Players Leroy Edwards and Charley Shipp earned First Team All-NBL honors.
