Mill Hill School is a 13–18 co-educational private, day and boarding school in Mill Hill, London, England that was established in 1807. It is a member of the Headmasters' and Headmistresses' Conference.

A committee of Nonconformist merchants and ministers, including John Pye-Smith founded the school, originally called Mill Hill Grammar School, for boys on 25 January 1807. They located it sufficiently distant of London at that time, because of "dangers both physical and moral awaiting youth while passing through the streets of a large, crowded and corrupt city". A boarding house was opened in the residence once occupied by Peter Collinson, with about 20 boys. John Atkinson was the first headmaster and chaplain until 1810.

Mill Hill School occupies a 120-acre (49 ha) site, part of which formed the gardens of Ridgeway House, the house of the botanist Peter Collinson. He was one of the most important importers of rare and exotic plants into English gardens. Many of the species that he introduced to Mill Hill in the 18th century continue to grow today in the grounds of the School. In 1746 Collinson planted Britain's first hydrangea on the grounds, now located adjacent to School House.

The estate was purchased by the botanist Richard Salisbury in 1802, Ridgeway House became the setting for a long-running scientific dispute between the new owner and his guest, James Edward Smith. The flora of Mill Hill was supplemented by the work of the amateur botanist Richard William Bowry Buckland (died 1947), governor of the foundation from 1878 to 1889, who cultivated a garden in the south-west of the school's grounds for the enjoyment of future generations. He wrote in his diary:

In years bygone I pray to thee,
This willow here, my legacy
As I have sat, pray sit thee.
In shaded splendour
Millhillians; rest hither.

— (signed Richard Buckland)

In 1939, Mill Hill School's premises became a hospital. The school was evacuated to St. Bees School in Cumberland for the duration of the Second World War. Collinson House, a school for girls, was named for it. A St Bees Association was founded in commemoration of this period of evacuation in the school's history by Michael Berry and David Smith.

Mill Hill first admitted sixth form girls in 1975 and became fully co-educational in 1997. The BBC news website usually uses a picture taken at Mill Hill School for articles about boarding schools.

In 2005 the school was one of 50 of the country's leading independent schools which were found guilty of running an illegal price-fixing cartel, exposed by The Times. Together they had driven up fees for thousands of parents. Each school was required to pay a nominal penalty of £10,000, and all agreed to make ex-gratia payments totalling three million pounds into a trust. It is to benefit persons who were students at the schools during the cartel period.

In March 2007, Mill Hill celebrated its bicentenary. To mark the occasion, the school was granted a new coat of arms by Robert Noel, Her Majesty's Lancaster Herald.

In 2018, the school experienced controversy when it was featured in the music video of London rapper Stefflon Don. In it, she was shown nude in the changing room showers, dancing on tables in classrooms, and smoking marijuana in the dormitories.

Mill Hill School is divided into houses. These are:

• Burton Bank – Named to commemorate its original position on Burton Hole Lane
• Collinson – Named after Peter Collinson, who once owned what is now the estate
• Macgregor – Named after Mary Macgregor, the founder and first head of The Mount, Mill Hill International
