Sir Courtly Nice: Or, It Cannot Be is a 1685 comedy play by the English writer John Crowne. Rehearsals by the United Company were underway when the death of Charles II in February led to the closure of all theatres as a mark of respect. The play was eventually staged on 9 May at the Theatre Royal, Drury Lane. It is the tradition of the Restoration Comedy. A popular hit, it became a stock part of the repertoire for more than a century, with Colley Cibber and Anne Oldfield appearing in a celebrated 1709 revival.
