Dulwich Prep & Senior (DPS), formerly known as Dulwich Prep London (2011-2024) and Dulwich College Preparatory School (1885-2011), is an independent preparatory school in Dulwich, south London, England for boys aged 3–13 years, with a co-educational Nursery. The current Headmaster is Louise Davidson.

At the suggestion of the Master of Dulwich College, Thomas Mason opened Dulwich College Preparatory School (DCPS) for 13 pupils in January 1885.

In 1938 headmaster John Leakey established an evacuation camp in the orchard on his father-in-law's land at Coursehorn, near Cranbrook, Kent, where the affiliated Dulwich Prep Cranbrook still is today.

The school changed its name in September 2011 to Dulwich Prep London, having been previously called Dulwich College Preparatory School. Despite their close proximity and relationship, the school has no official link with Dulwich College, which has its own junior school for students between ages 7 and 13.

In May 2023, the school announced that it would be opening a senior school, starting with Year 9, in September 2025.

As of September 2024, the school renamed itself Dulwich Prep & Senior for the upcoming senior school. https://posts.gle/vgcpYb

The school has also renamed their tribes (houses). Chippeways became Phoenix, Deerfeet became Lammasu, Objiwas became Gryphon and Mohicans became Pegasus.
