John Allen (c. 1823–1870) was an American saloon keeper and underworld figure in New York City during the early-to mid-19th century. A former religious student, Allen was considered one of the most notorious criminals in the city and was known as the "Wickedest Man in New York". A public crusade against him, headed by lawyer and journalist Oliver Dyer, resulted in a reform movement known as the "Water Street revival".

The campaign, in which Allen and other notorious underworld figures had been "reformed" by religious leaders, was later revealed to be a fraud following exclusive exposés by The New York Times and the New York World forcing Allen to leave the city.
