Aldwych ( /ˈɔːldwɪtʃ/) is a place and road in the City of Westminster in London, England.

Aldwych, the road, is a crescent, connected to the Strand at both ends. At its centre, it meets the Kingsway. Buildings along its length are:

Nearby, in the Strand, is the now-disused Aldwych tube station.

Its official name is "Aldwych" but the road is sometimes colloquially referred to as "The Aldwych", rather in the same manner that "Strand" is often referred to as "The Strand".

The name, "Aldwych", derives from the Old English eald and wic meaning 'old trading town' or 'old marketplace'; the name was later applied to the street and district. It was recorded as Aldewich in 1211. In the seventh century, an Anglo-Saxon village and trading centre named Lundenwic ("London trading town") was established approximately one mile to the west of Londinium (named Lundenburh or "London Fort" by the Saxons) in what is now Aldwych. Lundenwic probably used the mouth of the River Fleet as a harbour or anchorage for trading ships and fishing boats.

Stephen Thomas Ward (19 October 1912 – 3 August 1963) was an osteopath and artist who became notorious as one of the central figures in the 1963 Profumo affair, a British public scandal which profoundly affected the ruling Conservative Party government. Ward introduced the married British cabinet minister and MP John Profumo to a showgirl named Christine Keeler at a house party hosted at Lord Astor's country home, Cliveden, in the summer of 1961. Profumo's subsequent sexual relationship with Keeler and his false statement to the House of Commons regarding its nature led to Profumo's resignation.

Following the Profumo scandal, Ward was charged with living off the profits of prostitution ("immoral earnings"). Ward committed suicide by overdosing on sleeping tablets on the last day of the trial.

Ward was the son of Arthur Evelyn Ward, Canon of Rochester Cathedral. He was educated at Highgate School in London. In 1920 the family moved to Torquay when Ward's father became Vicar of St. Matthias.
