Rolland A. "Rollie" Seltz (born January 25, 1924) is a retired American basketball player who played in the National Basketball Association (NBA) in its first year of existence.
Born in McIntosh, Minnesota, Seltz attended Humboldt Senior High School in Saint Paul. He attended Hamline University, where he was named an All-American by Converse in 1946. Seltz and teammate Howie Schultz stirred up controversy during the 1944–45 season as the two men played minor league baseball during their college careers. At the time, this was viewed in some quarters as a violation of their amateur status for college basketball. During college, Seltz played for the Duluth Dukes, Jamestown Falcons, Rochester Red Wings, Lynchburg Cardinals and Allentown Cardinals, batting .266 in 400 games.
Following his college career, Seltz joined the Anderson Duffey Packers of the National Basketball League (NBL) in 1946. He played two seasons for the Packers and one for the Waterloo Hawks, averaging 8.1 points per game in 1948–49. The following season, Seltz re-joined the Packers as the team moved to the new National Basketball Association (formed through a merger of the NBL and the Basketball Association of America). Seltz averaged 7.8 points per game during the 1949–50 NBA season.
