It was the second high school built in Terrebonne Parish after the parish's sole high school, Terrebonne High School, became overcrowed with an influx of students from the lower areas of the parish.
The school was designed by the architectural firm of Curtis and Davis, who later designed the Louisiana Superdome in New Orleans.
South Terrebonne High was officially opened in 1961, with the first graduating class commencing in 1962. Most of the first graduating class were transferred into South Terrebonne for their senior year when the district was reapportioned, and some students delayed their graduation from Terrebonne High in 1961 in order to graduate in the first graduating class at the new school in 1962.
In 1968 Southdown High School (originally Houma Colored High School), which educated black students in Terrebonne Parish, closed. Students were moved to South Terrebonne High and Terrebonne High School.[2]
Prior to 1988, South Terrebonne housed students in their sophomore, junior, or senior year. Once Ellender Memorial High School was expanded from a junior high school to become the parish's fourth high school, freshmen were then added to South Terrebonne. Today, the school houses over 1,000 students in grades 9-12, with 8th graders added in special education or advanced gifted classes.
Terrebonne High School - Since 1961, when athletics began at South Terrebonne, it has continued to be the oldest living intra-parish rivalry. The schools are both known for their intense "dislike" for one another, on and off the fields of play.
Ellender Memorial High School - This became most recent rivalry, especially in football, when Ellender became a high school in 1988. Both schools share a common football field located at South Terrebonne's campus. South Terrebonne has dominated Ellender since 1996, and has only lost one game to Ellender since then. Also, each school's student body competes in the "Battle for the Spirit Stick", where students purchase construction paper chain links in each schools colors to adorn the stadium on game night. The school who sells the most links maintains the Spirit Stick until the following year. This is where the South Terrebonne's tradition of "Camo-Day" originated. Each South Terrebonne/Ellender football game the students at South Terrebonne High School dress in their camouflage clothing, paint their faces, and decorate the school with a swamp theme. Both schools have pep rallies for this occasion that show the "special" rivalry between the two schools.
South Lafourche High School - This is the lesser-advertised rivalry in the area. Both are the southernmost high schools in their respective parishes. Each school has a history of surprising wins and devastating losses to the other in many sports. The rivalry is further fueled by each school's fan base, where old-fashioned "in your face" mockery is steeped in the area's Cajun culture.
School songs
The South Terrebonne High Fight Song was written from the combination of fight songs from two universities. The first verse was taken from the Victory March of the University of Notre Dame, while the second verse was taken from The Victors of the University of Michigan.
