With rapid growth in Seminole in the late 1950s and early 1960s, it became necessary for the newly suburban area to have its own high school.

The original school consisted of what is now the main building where the administration offices are located and the front cafeteria.

The current "Warhawk" stadium was built in 1967 after a lengthy fundraising drive (Seminole Pow Wow).

The Seminole High School Warhawk Marching Band has won the FMBC Florida State Class 4A Championships in 2018, 2012, 2011, 2006, and more.

They were the grand champions at the 2017 USBands Southern States Regional Championship in Chattanooga, Tennessee.

The Seminole High School Drama and Musical Theatre Department, also known as Troupe 3039 at competitions, usually put on at least one musical a year, and compete at the Florida Thespians District and State competitions every year.
