Mount Street Gardens is a public garden off Mount Street in the west of the Mayfair area of London, England. The gardens were created in 1889 out of a former burial ground of St George's, Hanover Square, and named after the Mount Field, an area including a fortification dating from the English Civil War named Oliver's Mount.

Mount Street is an east–west, quite narrow, archetypal street in the Mayfair district of the City of Westminster, London fronted by many mid-rise buildings, mostly of a narrow frontage. The sides of two very grand hotels flank part of either end of the street. Small, high-end property businesses, investment funds and accountancy businesses punctuate the buildings as well as a row of traditional businesses and conversion-style mansion block apartments or, more generally, authentic such homes.
