Enid High School (EHS) is a public tertiary school in Enid, Oklahoma, U.S., operated by the Enid Public Schools school district. With a student body of about 2035 in grades 9–12, Enid High School has a matriculation rate of about 65 percent. Some graduates continue their education at University of Oklahoma, Oklahoma State University, or other establishments in Oklahoma. In recent years some have gone to West Point, Princeton University, Trinity University (Texas), Texas A&M Maritime Academy and Yale University.

The school district - Enid High's attendance zone - covers central-west Enid and some unincorporated areas.

EHS began as a tent school shortly after the land run in 1893, operating out of various locations throughout Enid including an opera house and a Baptist church. Between 1906 and 1912, classes took place in the "old" Lincoln school, now long-demolished, at 600 North Independence. By February 1912, the high school's current building was constructed. It was accredited by the North Central Association of Colleges and Secondary Schools in 1911, and holds the distinction of being the second high school in Oklahoma to be accredited by the organization. Enid High operated as a segregated school district from 1896 to 1959 with black children attending Booker T. Washington, Douglass and George Washington Carver Schools.

In 1943, a fire broke out, damaging the building. From 1943 to 1948, classes were held at Emerson and Longfellow Junior High Schools, displacing the seventh graders, who remained at their respective elementary schools. The school finished restoration in 1948, added a gym in 1950, an auditorium in 1953, a music building in 1991, and a large food court in 2005 to accommodate a new closed campus policy. During these times several new class rooms were also added. The building did not have air conditioning until a bond was passed in 1997.

In 2017, 200 of the students were Marshallese. By 2014 the school had a student club where Marshallese students taught the overall student population about their culture. Circa 2014 a multicultural choir was formed.

Enid High School has several sports programs including American football, baseball, basketball, bowling, cheerleading, cross country, golf, marching band, track and field, tennis, soccer, softball, swimming, volleyball, show choir, and wrestling.

The basketball, wrestling, and volleyball programs were played in the historic Mark Price Arena until March 23, 2008, when the athletic director, Bill Mayberry, made the decision to move the home games and events to the athletic village on the Northern Oklahoma College campus, due to the deteriorating condition of the arena. The Plainsmen American football and soccer programs play in one of the oldest stadiums in the state, D. Bruce Selby Stadium.
