Charles-Jacques-Louis-Auguste Rochette de La Morlière, called "Le Chevalier" , (22 April 1719 – 9 February 1785) was an 18th-century French playwright.

An unscrupulous schemer, La Morlière first sought the support of the party of Voltaire, applauding the verse of the master, and when he found himself sufficiently established at café Procope, became an entrepreneur of success and dramatic falls.

In order to replace the whistle that the police did not always tolerate, he had imagined a sort of protracted yawn that produced a disastrous effect.

Believing himself master of the theater, La Morlière had the idea to use his means of action for his own account and wrote comedies but, despite all the efforts of his cabal, they fell, and with them his influence.

Accused of baseness and cowardice and also of relations with the police, he was abandoned by everyone and ended his life in deep poverty.
