Clayesmore School is a co-educational private school for pupils aged 8 – 18 years, in the village of Iwerne Minster, Dorset, England. It is both a day and boarding school and is a member of The Headmasters' and Headmistresses' Conference (HMC).

The school was founded by Alexander Devine in 1896 in Enfield, Middlesex. After moving to Pangbourne, Berkshire and then to Winchester, Hampshire it finally moved to Iwerne Minster for the summer term of 1933. In 1974 it was joined on the Iwerne site by Clayesmore Preparatory School, originally Charlton Marshall School, which had been founded in 1929 by R.A.L. Everett. In the following year the school became co-educational.

As of 2023 there are 400 pupils in the senior school (ages 13–18) and 150 in the prep school (ages 3–13). The current head is Joanne Thomson. The school is situated on a 62-acre (250,000 m2) campus.
