Charles E. Hallstrom (January 22, 1863 – May 6, 1949), nicknamed the "Swedish Wonder", was a Swedish Major League Baseball player who pitched one game for the Providence Grays of the National League. The Grays were in need of a pitcher for that day's game versus the Chicago White Stockings, and used Hallstrom, a local Chicago amateur player. Hallstrom is the first of four Major League Baseball players born in Sweden. He was born in Jönköping, Sweden, and died in Chicago at the age of 86. He is interred at the All Saints Cemetery in Des Plaines, Illinois.
