Sloane Square is a small hard-landscaped square on the boundaries of the central London districts of Knightsbridge, Belgravia and Chelsea, located 1.8 miles southwest of Charing Cross, in the Royal Borough of Kensington and Chelsea.

The bulk of Chelsea, especially the east end more local to Sloane Square, is architecturally and economically similar to South Kensington, Belgravia, St James's, and Mayfair. The largely retail at ground floor Kings Road with its design and interior furnishing focus intersects at Sloane Square the residential, neatly corniced and dressed façades of Sloane Street leading from the Victoria Embankment promenade to the small district of Knightsbridge. On the northern side of the square is the Sloane Square Hotel.

Estates on all sides are made up of ornate, luxuriously furnished private apartments set behind railings — a minority of these remain combined to form large townhouses, primarily in amongst those of rows of not more than four storeys. Gothic, classical and Edwardian architecture mix; the area has grown piecemeal, including in infill, under strict character and aesthetic demands of local urban planning. Elements of almost every street were reinstated, in similar style, after the London Blitz.
