Charles "Kid" Keinath (November 13, 1885 – April 1966) was an American college athlete who was a four-time All-American in basketball while at the University of Pennsylvania. He also won national championships in both basketball (1907–08) and football (1908) at Penn. In 1907–08, the basketball team finished 24–4 and was retroactively named the national champions by the Helms Athletic Foundation. Then, in 1908, the football team finished 11–0–1 and was named co-national champions with Harvard and LSU with Keinath leading the team as quarterback. He was team captain as a senior for the basketball team and led the Quakers to a 22-game winning streak that spanned between the 1907–08 and 1908–09 seasons.
