Sullivan East High School is a 9th–12th grade public high school located in Bluff City, Tennessee, United States.

In October 2002, Sullivan East High School was forced to temporarily close its doors for about six weeks and underwent $600,000 worth of repairs when some students became ill and several classrooms tested positive for black mold.

The cause was later determined to be poorly insulated cold water piping.

Classes were held in the skyboxes at nearby Bristol Motor Speedway until the necessary repairs were completed.

In 2021, West Ridge High School opened.
