Le roi malgré lui is an opéra-comique in three acts by Emmanuel Chabrier of 1887 with an original libretto by Emile de Najac and Paul Burani. The opera is revived occasionally, but has not yet found a place in repertory.

Alexis-Emmanuel Chabrier was a French Romantic composer and pianist. His bourgeois family did not approve of a musical career for him, and he studied law in Paris and then worked as a civil servant until the age of thirty-nine while immersing himself in the modernist artistic life of the French capital and composing in his spare time. From 1880 until his final illness he was a full-time composer.
