Red River High School (RRHS) is a public high school located in Grand Forks, North Dakota, United States.

The name Roughriders is a reference to former President Theodore Roosevelt, who spent a portion of his life in what would become western North Dakota.

Circa 1992 there was a bond proposal to build more space at Red River High for $13,500,000.

Dual credit and Advanced Placement classes are available in several areas of study.

*RRHS and Central High School have combined teams in several sporting areas, due to low participation numbers, known as the "Knightriders".
