Choctawhatchee originally opened its doors in Shalimar, Florida, on September 22, 1952. It was filled over its capacity of 500 students, enrolling 625 students in grades 7 through 12. The local news held a contest to name the school, and thus Choctawhatchee, or "coming together," was picked. Later it was relocated to its current location in Fort Walton Beach, Florida with the old site becoming what is now Meigs Middle School.

In 1990, the football team was the 5A State Champion.

The school's marching band, known as the Style Marchers, were back-to-back 5A Florida State Champions in 2004–05, 2005–06, and were runners-up for 2006–07. The Stylemarchers came back on top for another back-to-back 5A Florida State Championship for 2007–08, 2008–09. The Choctawhatchee Style Marchers also marched at the 2009 Macy's Thanksgiving Day Parade in N.Y. The choral and band departments annually send students to All-State and make superiors at their respective district festivals. The winter percussion ensemble has placed in the top 13 at the WGI World Championships since 1998. The drumline won 1st in she Scholastic Open competition in 2002 and were promoted to Scholastic World for the following year. In 2003, they placed 3rd, in 2004 they placed 12th, in 2005, 8th in 2006, 6th, and in 2007 &2008 they placed 4th in the Scholastic World Division. In 2019, the Drumline returned to Dayton, Ohio for the first time since 2013, placing 14th in finals. The Winter Color Guard has also been a finalist for many years at the WGI World Championships, including 2007, 2006, 2004, 2003. In 2014 the Winter Guard was awarded 13th in world class at WGI World Championships.

WBGI members make a news show daily and produce many other promotional videos for the school. In 2018, WBGI made a spirit video that won Choctaw the Sunshine State Showdown.

The school newspaper, Smoke Signals, won a top award from the Florida Scholastic Press Association in 1998.

The Tomahawk Yearbook has won numerous state and national awards.

At the beginning of each home football game, the school Indian, or student mascot, rides a horse across the field and throws a spear midfield. The idea was borrowed from Florida State University where during pregame the university symbol, Chief Osceola, rides Renegade the horse to plant a flaming spear at midfield.

In front of the school stands three totem poles just outside the front office. They are a symbol of school pride and represents various aspects of student life and have withstood hurricanes, attacks by rivals, and continue to serve as an emblem of the Choctaw High School family.

Also in front of the school are engraved bricks, purchased by students and then engraved so that they may forever be a part of the school.

The Alma Mater was written during the school's first year by the band director, Jim Leonard. The tune is a World War I song, "Long, Long Trail Awinding." In 1956, Bryan Lindsey came to Choctaw as choral director, and began writing words to "Big Green Indian." Lindsey collaborated with Leonard to compose the song. It became the school's fight song.
