El Dorado High School is an accredited comprehensive public secondary school located in El Dorado, Arkansas, United States. The high school serves students in grades 9 through 12 for the community of El Dorado and surrounding unincorporated communities in Union County, Arkansas. The school is administered by the El Dorado School District. Its principal is Sherry Hill. The school has won 26 state athletic championships.

The assumed course of study for students follows the Smart Core curriculum developed by the Arkansas Department of Education (ADE). Students complete regular (core and elective) and career focus courses and exams, and may select Advanced Placement (AP) coursework and exams that provide an opportunity for college credit.

In 2011, El Dorado School District and its high school were recognized in the AP District of the Year Awards program in the College Board's 1st Annual Honor Roll. This consisted of 388 U.S. public school districts (two in Arkansas) that simultaneously achieved increases in access to AP courses for a broader number of students, and improved the rate at which their AP students earned scores of 3 or higher on an AP exam.

In March 2009 a new high school construction began; it was completed in June 2011. The new school is for 1,500 students and is a 320,000 square feet (30,000 m) two-story structure made of wood, masonry, concrete and steel. Located in the original 1920s oil field, the project included a 2,000 seat arena/gymnasium, 450-seat fine arts auditorium and seven classroom zones on a site totaling 62 acres.

Murphy Oil's $50 million gift to education in El Dorado set the wheels in motion for the new school.

The new EHS also includes more than 100 classrooms and instructional spaces, six dedicated computer labs, media center, theater with sloped and tiered lecture seating, basketball arena, 75-seat “black box” theatre, 13 science labs, “Main Street” circulation corridors and central octunda, and 8,000 sq ft (740 m) student dining/commons with serving area.

The El Dorado High School mascot and athletic emblem is the wildcat, with purple and white serving as the school colors.

The El Dorado Wildcats and Ladycats compete in several interscholastic athletic activities, including football, cross country, baseball, girls' softball, basketball, golf, track & field, girls' volleyball, tennis, and soccer. In 2012–14, EHS was a member of the 6A Classification and the 7A/6A South Conference as administered by the Arkansas Activities Association.
