Riverside High School is a public high school located in Durham, North Carolina. The principal of Riverside High is Dr. Gloria Woods-Weeks, who joined as principal in 2021. Current members of the school administrative team include Dr. Will Okun, Mr. Darryl Bradshaw, Ms. Jasmine McKoy, and Mrs. Tammy Patterson. The school enrolls students from grades 9–12. The school was founded in 1991 and became one of the seven Durham Public High Schools.

Riverside High School opened in 1991 (the first class graduated in 1993) and currently enrolls approximately 1,700 students. It is one of seven high schools in the Durham Public School System. The school offers classes on a block schedule on a semester basis, with students taking 4 classes—generally 2 core and 2 elective—each semester. Riverside is an accredited school and is also home to the Durham Public Schools' engineering program, which uses the national Project Lead the Way curriculum.

Riverside's sixteen sports teams are part of the PAC-6 Conference, which includes schools in Durham County and the neighboring counties of Orange and Person. The school has fielded several state champions in football, wrestling, men's lacrosse, volleyball, and swimming.

In 2017 the principal, Tonya Williams, proposed a "SMART Lunch" program where there is a single lunch period that is one hour long and students are free to attend certain clubs, replacing the former scheme where students are assigned to one of three lunch slots at different times in the school day. It was enacted in the fall of 2019. In summer 2023 Dr. Gloria Wood-Weeks after much deliberation with her administrative team and staff, rebranded Smart Lunch to become Pirate Block. The rationale of the rebranding is to provide more structure to all students and still allow them to participate in clubs as well as receive tutoring in classes. It features two lunch periods and highlights a different class period each day to allow an opportunity for each student to receive support in that class. During Pirate Block, students report to the featured class for that day. Attendance is taken and students are dismissed for lunch, dismissed to a club they have joined, or they begin with receiving tutoring from their teacher. While half the student body is at lunch the other half is participating in Pirate Block activities. The days are as follows: on Mondays first period is the featured class for Prate Block on Tuesdays and Wednesdays is second period, on Thursdays is third period, and on Fridays is fourth period. Pirate Block was enacted Fall 2023

In 2007, Riverside was ranked as the 834th high school in America by Newsweek.

In 2011, Riverside's Student Newspaper, The Pirates' Hook, was awarded the best student run newspaper in North Carolina.
