Edge Grove School, simply Edge Grove, is a 3–13 mixed, private, day preparatory school in Aldenham, Watford, Hertfordshire, England. It was established in 1935 and set on 48 acres.
The boys and girls are organised into five houses: Hedgerows, Sarnesfield, Churchill, Stratton and Gills.

History
Mr John Skey bought the land on which the current property in 1733 and built the main block of what now stands as the main house. This house was then sold by his sons to Mr Thomas Hake some time in the late 1780s. The American financier and banker John Pierpont Morgan bought the property in 1912 and rented it to Mr Richard Bennett. Bennett converted the house with around £90,000 leading to the house as it stands currently. When it came to settling his estate, Morgan arranged for the council to take the freehold, specifying it should be used as an independent school.

The current headmaster as of January 2023 is Ed Balfour, formerly Head at Beechwood Park School and Northbourne Park School.

Facilities
The school has a large sports hall, all-weather tennis/netball courts, an AstroTurf pitch, 9 acres of playing fields, indoor & outdoor cricket nets and a heated outdoor swimming pool.
In November 2019, it recently opened £3.6m lower school building for Years 3 and 4.
