Sudbury Grammar School was a boys' grammar school in Sudbury. The school was founded in 1491. In 1972, the school was amalgamated with other local schools to form Sudbury Upper School.
It was a boys' grammar school. The analogous school for girls was Sudbury High School, which later became a bi-lateral school. Another nearby former grammar school was Woodbridge Grammar School. There was flexible transfer from the Sudbury Secondary Modern School, a boys' school - upwards and downwards.
In December 1966, seven sixth form boys made a formal protest about the admission of Prince Charles to Trinity College, Cambridge, whom they claimed had entered by a backdoor entry method.
