John Foster Dulles High School, more commonly known as Dulles High School, is a high school in Sugar Land, Texas. It was the first site purchase and new build, in the 1950s, of the newly formed Fort Bend Independent School District, which held its first graduation in 1960. The first class to graduate from Dulles itself was 1962. Its mascot is the Viking, and its team colors are red, white and blue. Its slogan was "Set Sail" up until the end of the 2018–2019 school year, but was changed to "Viking True" the next school year. Dulles was named a National Blue Ribbon School in 1984–85.
