Elizabethton High School was founded in 1908 as a combined elementary and high school. It became a High School in 1925 after a bond allowed the city to separate the elementary and high school. In 1939, a new building for Elizabethton High School was constructed. Today, the building remains as T.A. Dugger Jr. High School. In 1999, the school made national headlines after students created a nativity scene with cat cadavers for a decorating contest. After three days, a group of students took down the display. They were suspended afterwards. ==Demographics==

Cyclones are the school mascot. In 1938, Elizabethton High School received its first state championship title for football. This would be their only state championship in football until 2019, when Coach Shawn Witten would take his team to a 15-0 undefeated season and the schools first state title in 82 years. They would go back-to-back in 2020, but would come short the following year in 2021. During that three-year stint, the Cyclones at one point had an undefeated streak of 31-0 until it was broken by the Greeneville Greene Devils in 2021. The Cyclones Football team played at Brown-Childress Stadium at the former high school site, now T.A. Dugger Jr. High School, from 1947 until 2014, when the team moved to the newly built Citizens' Bank Stadium on campus. The Cyclones boys' track and field team would take home a state title in 2004 and 2005. 2004 also saw the boys' cross country team win its first state title as well. In 2014, the Lady Cyclones basketball team won its first state title with a record of 32-3, as well as Kayla Marosites winning the MVP for the 2014 finals game and the TSSAA Miss Basketball awards the following two years. In 2026, a new athletic center named for former head football coach, Dave Rider, was officially opened. ==Alumni==
