Grenville College was an independent boarding and day school situated in Bideford, Devon, England.

Grenville College was founded in 1954 as a boys’ school by Messrs O. Dromgoole, B. Spain, and W. G. Scott.

The college is named after the Elizabethan sea captain, Sir Richard Grenville, who came from Bideford.

This included the setting up of a specialist dyslexia department, which has now been part of Grenville College for 38 years and has earned a national reputation for its excellence.

The former Stella Maris school included the listed buildings Northdown Hall[1] and York House[2] on Northam Road.
