Bergen katedralskole (English: Bergen Cathedral School) is an upper secondary school in Bergen, Norway. Located in the city centre, next to Bergen Cathedral, the school has about 465 students, 55 full-Time teachers, and 5 administration personnel, including the headmaster, Hans Peder Vibe.
The school is thought to have been founded in 1153 by Nicholas Breakspear (later Pope Adrian IV), making the school the second oldest in Norway together with Oslo katedralskole and Hamar katedralskole, which were founded the same year, one year after the founding of Trondheim katedralskole.
Although the earliest written records documenting the school's existence date back to 1288, Bergen katedralskole is believed to have been founded in 1153 by Nicholas Breakspear, who became Pope Adrian IV in 1154. It was founded as a theological school for the education of priests. Pupils would start attending the school around the age of seven. Until the school reform in 1806, the school was tied to the church.
