Milton Abbey School is a private school for day and boarding pupils in the village of Milton Abbas, near Blandford Forum in Dorset, in South West England. It has 224 pupils as of September 2023, in five houses: Athelstan, Damer, Hambro, Hodgkinson and Tregonwell. The school was founded in 1954 and is co-educational.

The school has facilities that include a golf course, a 15th-century dining hall, an Abbey chapel that can be traced back to the 10th century and grounds designed by Lancelot "Capability" Brown. The main house was built by Joseph Damer, 1st Earl of Dorchester.

Milton Abbey School offers the English curriculum of GCSEs, A-levels, and BTECs. The school was named BTEC School of the Year 2019 by BTEC awarding body Pearson. In 2022, Milton Abbey School was noted as having the highest proportion of BTEC student uptake of all English independent schools.

The Abbey forms the central heart of the school. A chapel service takes place for the whole school twice a week. On Monday there is a house assembly and Wednesday a whole school assembly. On Sundays the school gathers for a formal Sunday worship, and there are regular communion services throughout the term. The school, although a Church of England foundation, welcomes people of any faith, and also of none.

The abbey church is built in a mixture of Ham stone, Chilmark stone and flint and consists only of the choir, central tower and transepts. Its style is mostly decorated gothic dating from the mid-14th century with some 15th-century details in the tower and north transept. The eastern Lady Chapel was demolished after the suppression and some alterations were made by Wyatt in the late 18th century. The Earl and Countess of Dorchester were also generous to the church, and their joint tomb, designed by Robert Adam with sculpture by Agostino Carlini, is to be found in the north transept. Perhaps the most striking feature of the church's interior, however, is its south window, designed as a Tree of Jesse by Augustus Pugin. Other features of interest are the 14th-century pulpitum and sedilia, the 15th-century reredos and pyx canopy, and the 16th-century monument to John Tregonwell.

Milton Abbey (fully, the Abbey Church of St Mary, St Samson, and St Branwalader) in Dorset was a Benedictine foundation, but only part of the church now survives and is used as the Milton Abbey School chapel. A college of secular canons was founded here by King Athelstan, in 933, and there are two medieval paintings of the king and his mother in the chancel. This foundation was replaced in 964 by a Benedictine monastery by King Edgar. The medieval church burned down in 1309, and although rebuilding started straight away it did not reach its present size until about 1400.

One of the church's benefactors was Sir John Tregonwell, whose family came into the possession of the buildings in 1540 following the Dissolution of the Monasteries in 1539. Tregonwell fell from the roof of the church in a childhood accident, but his life was saved when his wide pantaloons filled with air and broke his fall. In thanks, he bequeathed his library to the church. Sir John also was buried in an altar tomb in the Abbey Church.

In 1752, the buildings were bought by the Damer family: in 1771, to make way for a new house and landscaped estate, the 1st Baron Milton (later 1st Earl of Dorchester) demolished the remaining abbey buildings, keeping only part of the church as a private chapel, and the adjacent market town of Milton (creating Milton Abbas to rehouse the former inhabitants) in 1780. The new house was designed by William Chambers and the gardens by Capability Brown. Several members of the Damer family were buried in the family vault in the Abbey Church.

In 1852, the merchant banker Carl Joachim Hambro acquired Milton Abbey to make it his family home. He set about a major restoration programme, including an extensive refurbishment of the Abbey itself. The Hambro family developed and lived at Milton Abbey until 1932, when it was sold and for a while they moved to Hedge End Farm nearby, followed by a permanent move to Dixton Manor in Gloucestershire.

Milton Abbey School was the setting for "Bamfylde School" in the 1980 13-part TV series of R. F. Delderfield's To Serve Them All My Days. It also featured in the first of the Ripping Yarns by Michael Palin and Terry Jones, titled Tomkinson's Schooldays and in the 1994 film version of The Browning Version with Albert Finney and Greta Scacchi.

The parklands were landscaped in the late 18th century by Capability Brown. They are Grade II* listed in the National Register of Historic Parks and Gardens.

In 2009, the school started to develop a farm, which is worked on by staff, to promote environmental awareness and work towards an element of self-sufficiency. Traditional vegetables are grown, in addition to herbs, cutting flowers, fruit and some crops. The estate also has a small number of pigs, sheep, chickens and ducks.

The school has a golf course which winds around the main house and the Abbey Church. Designed by Peter Alliss and opened in 1972, it is a nine-hole course with par-3 and par-4 hours, which is used by pupils and by visitors, who are required to pay a small green fee. The school employs a PGA Professional, who helps to tutor the students.
