Robert Alexander Lewcock (1846–1932) was a British architect.
Lewcock was the architect responsible for the Black Lion, a Grade II* listed public house at 274 Kilburn High Road, Kilburn, London. It is on the Campaign for Real Ale's National Inventory of Historic Pub Interiors.[1]
It was built in about 1898, with the interior carved panels by Frederick T Callcott, with whom Lewcock worked on a number of projects.[2]
