Sumner High School is a St. Louis public high school that was the first high school for African-American students west of the Mississippi River in the United States. Together with Vashon High School, Sumner was one of only two public high schools in St. Louis City for African-American students and was segregated. Established in 1875 only after extensive lobbying by some of St. Louis' African-American residents, Sumner moved to its current location in 1908. It has historically also been known as Charles H. Sumner High School, and Sumner Stone High School.

Vashon High School is a high school of the St. Louis Public Schools in St. Louis, Missouri. When it opened in 1927, it was the second high school for black students in St. Louis.
