George Henry Jewett II (April 1870 – August 12, 1908) was an American athlete who became the first African-American football player at both the University of Michigan and Northwestern University and in the Big Ten Conference. He played for the Michigan Wolverines as a fullback, halfback, and field goal kicker in 1890 and 1892 and was considered one of Michigan's greatest players in the pre-Fielding H. Yost era.
