Fidelity Manor High School was a high school for African American children in Galena Park, Texas and a part of the Galena Park Independent School District (GPISD). It opened in 1955 and was the only black high school in the district. As part of desegregation in the United States the school merged into the previously all-white Galena Park High School in 1970. The district also closed Fidelity Elementary School at that time.
