Marwood (Girls Sixth Form Boarders) Russell (Girls Day Sixth Form) Courtenay (Boys Sixth Form) Newton (Boys YR9-11) Kelly College was a coeducational independent school in the English public school tradition situated in the outskirts of Tavistock, Devon, with around 350 students ranging from ages 3 to 18.

[1] The college had twenty acres (eight hectares) of landscaped grounds, including playing fields, set on the edge of Dartmoor and including a stretch of the River Tavy, and four separate senior boarding houses, and a junior house, each with its own facilities.

The last headship was of Mr Mark Semmence who joined the college in 2013.

The school was founded in 1877 after Admiral Benedictus Marwood Kelly left the great part of his real and personal estate to Trustees, founding a charity which he directed should be called "The Kelly College", which should be for the education of the "sons of Naval officers and other gentlemen".

The school opened in October 1877, under the Headmastership of Robert West Taylor, late fellow of St John's College, Cambridge, with twelve boys on the school roll.
