West Dulwich (/ˈdʌlɪtʃ/ DUL-itch) is a neighbourhood in South London on the southern boundary of Brockwell Park, which straddles the London Borough of Lambeth and the London Borough of Southwark. Croxted Road and South Croxted Road mark the boundary between Southwark to the east and Lambeth to the west. The suburb of West Dulwich dates back to the 17th century when the often flooded land known as Dulwich Common was acquired and drained by Edward Alleyn's estate.
