Smithfield, properly known as West Smithfield, is a district located in Central London, part of Farringdon Without, the most westerly ward of the City of London, England.

Farringdon Without is the most westerly ward of the City of London, England. Its suffix Without reflects its origin as lying beyond the City's former defensive walls. It was first established in 1394 to administer the suburbs west of Ludgate and Newgate, including West Smithfield and Temple. This was achieved by splitting the very large, pre-existing Farringdon Ward into two parts, Farringdon Within and Farringdon Without. The large and prosperous extramural suburb of Farringdon Without has been described as having been London's first West End.
