Founded by King Henry VIII in 1541, The King's (The Cathedral) School is a state-funded Church of England Cathedral Chorister School located in Peterborough, England. It is the chorister school for Peterborough Cathedral. Former pupils are known as Old Petriburgians.

Although for centuries a boys-only grammar school, "Kings" is now mixed and has a junior department in Madeley House. Madeley House was previously the home for boarders, and many cathedral choristers were boarders there; but now the school has day pupils only.

As part of the wider chapter of Peterborough Cathedral, the headteacher retains his own stall in the quire today.
