The origin of the school's name is uncertain; however, it may be due to its location, at the time it opened Sunset was the westernmost school in the DISD, and the subdivision surrounding the school on the western side of Dallas was called 'Sunset Heights'.The school opened in 1925 with 1,400 students and 39 teachers as southwest Oak Cliff became increasingly developed. At the time it was the high school with the largest capacity in DISD; it had the same general architectural plan as Forest Avenue, North Dallas, and Oak Cliff (now W. H. Adamson) high schools.
