Hammersmith is an urban centre in the London Borough of Hammersmith and Fulham in west London, England, in the United Kingdom, approximately five miles (eight kilometres) west of Charing Cross on the north bank of the River Thames. One of west London's key transport hubs and commercial and employment centres, and home to several multinational company offices, it is focused on the two London Underground stations, bus station and road network node at Hammersmith Broadway.

It is bordered by Shepherds Bush to the north, Kensington to the east, Fulham to the south and Chiswick to the west, and is linked by Hammersmith Bridge to Barnes in the southwest.

It has for some decades been the main centre of London's Polish minority.
