Rotorua Boys' High School (RBHS) is a state school educating boys from Year 9 to Year 13. It is situated just outside the Rotorua CBD at the intersection of Old Taupo Road and Pukuatua Street in Rotorua, New Zealand. The school is governed by an elected School Board, of which the Principal is ex officio a member under guidelines laid down by the New Zealand Ministry of Education. With Māori enrolment exceeding 75% of the school’s intake, the largest per capita in New Zealand, RBHS has been a longstanding recipient of funding from its Ngāti Whakaue endowment that assisted the construction of the school’s 104-bed hostel, and the purchase of a computer laboratory. RBHS is noted for its performance in sport, with 4 Olympians among its notable alumni, and for having won the Prime Minister of New Zealand Supreme Award for Excellence in Education and the Excellence in Leading Award, making it the top school in the country for 2019. Its current principal, Chris Grinter, is the longest serving in the school's history, and in 2022, he received a New Zealand Order of Merit for services to education and Māori.

Single-sex education, also known as single-gender education and gender-isolated education, is the practice of conducting education with male and female students attending separate classes, perhaps in separate buildings or schools. The practice of single-sex schooling was common before the 20th century, particularly in secondary and higher education.
