Lonsdale Square is a traditional London square in Barnsbury, Islington, North London.
The square consists of tall brick town houses with distinctive steep gables, mullioned windows in white, arched front doors, and black railings. There is a garden in the centre of the square for use by residents.
The square was built between about 1838 and 1845, and was designed in Gothic Revival style by R. C. Carpenter. The square was built at the same time as the public house at the north end, currently called The Drapers Arms.
