Eccleston Square is a square in Pimlico, London.
The square dates to the 1830s, an integral part of Thomas Cubitt's planned design of “South Belgravia”, which is now called Pimlico. Cubitt designed many of the houses on the square and built and leased Nos 1-3 in 1836 and Nos 4 and 5 in 1842 all of which are grade II listed with English Heritage. The land was formerly part of the Grosvenor family estate, who owned land in Eccleston, Cheshire, from where it is thought the square takes its name.
The Buddhist Society has been based at no.58 since 1956.
There are two blue plaques in the square. The first is for Winston Churchill, who moved to Eccleston Square a year after marrying Clementine Hozier, and their first two children, Diana and Randolph, were born there.
The Eccleston Square Hotel is a grade II listed building at no.37.
