Charles Willard Stage (1868–1946) was an American attorney, politician, professional baseball umpire and amateur track athlete.
While attending Western Reserve University, Stage tied an amateur world record in the 100-yard dash and briefly became a National League baseball umpire in 1894.
After finishing law school, he was a private practice attorney and served in the Ohio House of Representatives in 1902–03 before returning to law practice.
Stage was married to Miriam Kerruish, one of the first women to practice medicine in Cleveland.
She died in 1929, and he retired after his most notable law clients (the Van Sweringen brothers) lost their fortune in the Great Depression.
He was sometimes known as Billy Stage, particularly in collegiate athletics and in baseball circles.
