The Metropolitan Borough of Wandsworth was a metropolitan borough under the London County Council. It covered the areas of Wandsworth, Streatham and Clapham.

When the metropolitan boroughs were replaced with larger London boroughs in the 1960s, this borough was split. The core area of Wandsworth became part of the London Borough of Wandsworth, but the areas of Streatham and Clapham became part of the London Borough of Lambeth.
