Frensham Heights School is a private school with a sixth form college located near Farnham, Surrey, England, run by the registered charity, Frensham Heights Educational Trust Ltd.

Unlike many HMC member schools, it has been coeducational and has taken both day and boarding pupils since its foundation.

The school was founded by Edith Douglas-Hamilton and established under joint headmistresses, Beatrice Ensor and Isabel King.

[citation needed] Based at a mock-Tudor mansion, built by the brewer Charles Charrington in 1898, and in its estate, the school is on a hill 2.5 miles (4.0 km) from the centre of Farnham but is actually in the village of Frensham.

Ben McCarey started as the full-time Head of Frensham Heights in September 2024.
