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.
Several structures in and adjacent to the gardens are listed Grade II on the National Heritage List for England. These include the fountain, two cisterns, and the two K2 telephone kiosks and the Portland stone gate piers with lamps at the entrance by South Audley Street.
