She Stoops to Conquer is a comedy play by Anglo-Irish writer Oliver Goldsmith. First performed in London in 1773, it is Goldsmith's best-known play and a cornerstone of both English literature and theatre classes in the English-speaking world. It is one of the few plays from the 18th century that has retained its popularity and is still regularly performed. Regarded as a classic of the period, the work has been adapted for films on numerous occasions, including in 1910, 1914, and 1923. The play is notable as the origin of the common phrase, "Ask me no questions and I'll tell you no lies."
The play was originally titled Mistakes of a Night and its events take place in one long night.
