Dulwich College is a public school (English private day and boarding school) for boys aged 2–18, in Dulwich, London, England. As a public school, it began as the College of God's Gift, founded in 1619 by Elizabethan actor Edward Alleyn, with the original purpose of educating 12 poor scholars. It began to grow into a large school from 1857 and took its current form in 1870, when it moved into its current premises.

The school is included in The Schools Index as one of the 150 best private schools in the world and among the top 30 senior schools in the UK. It is a member of both the Headmasters' and Headmistresses' Conference and the Eton Group.
