The Second Mrs. Tanqueray is a problem play by Arthur Wing Pinero. It utilises the "Woman with a past" plot, popular in nineteenth century melodrama. The play was first produced in 1893 by the actor-manager George Alexander and despite causing some shock to his audiences by its scandalous subject it was a box-office success, and was revived in London and New York in many productions during the 20th century.

Sir Arthur Wing Pinero was an English playwright and, early in his career, actor.
