City of London Freemen's School (CLFS) is a co-educational private school for day and boarding pupils, located at Ashtead Park in Surrey, England. It is a partner school of the City of London School and the City of London School for Girls, which are both independent single-sex schools located within the City of London itself. All three schools receive funding from the City's Cash. The school's head is a member of the Headmasters' and Headmistresses' Conference.

The Good Schools Guide described the school as "A traditional academic and sporty school in a stunning setting with impressive facilities but not at all elitist – in fact quite the opposite." In 2024, 33% of grades in A Levels were A* and 72% of grades were A*-A. In GCSEs, 40% of grades were 9, 67% were 8-9 (equivalent to A*) and 86% achieved 9-7 in GCSEs.
