1942–43 Sheboygan Red Skins season

The 1942–43 Sheboygan Red Skins season was the Red Skins' fifth year in the United States' National Basketball League (NBL), which was also the fifth year the league existed. Five teams competed in the NBL in 1942–43, the league's lowest number to that point (largely caused by the war), and the league did not use divisions.

The Red Skins played their home games at the Sheboygan Municipal Auditorium and Armory. For the second time in franchise history (1941), the Red Skins advanced to the NBL Championship. They then went on to win their first league title by defeating the Fort Wayne Zollner Pistons, two games to one in a best-of-three series. In the third and deciding game, Ed Dancker made the game-winning shot from the corner with less than five seconds remaining to win the championship.

Head coach Carl Roth won the league's Coach of the Year Award, while player Ken Buehler was named NBL Rookie of the Year. Ed Dancker (First Team), Buddy Jeannette (Second), and Ken Suesens (Second) earned All-NBL honors.
