Savile Row (pronounced /ˌsævɪl ˈroʊ/) is a shopping street in Mayfair, central London, famous for its traditional men's bespoke tailoring. The term "bespoke" is understood to have originated in Savile Row when cloth for a suit was said to "be spoken for" by individual customers. The short street is termed the "golden mile of tailoring", where customers have included Winston Churchill, Lord Nelson, Napoleon III and Mohammad Ali Jinnah.

Savile Row runs parallel to Regent Street between Conduit Street at the northern end and Vigo Street at the southern. Linking roads include Burlington Place, Clifford Street and Burlington Gardens.

Savile Row was built between 1731 and 1735 as part of the development of the Burlington Estate, and is named after Lady Dorothy Savile, wife of the 3rd Earl of Burlington. It originally ran from Burlington Gardens (then Vigo Lane) to Boyle Street, with houses only on the east side, but in 1937–8 it extended to Conduit Street, and in the 19th century houses were built on the west side. The original architectural plan is believed to have been drawn up by Colen Campbell, though Henry Flitcroft appears to have been the main architect of the street, under the supervision of Daniel Garrett, while Nos 1 and 22–23 Savile Row were designed by William Kent, who lived next door in No 2.Dr Livingstone was laid out in state in No 1, when it was the headquarters of the Royal Geographical Society, before being buried in Westminster Abbey.
