The Miser (French: L'Avare) is a five-act comedy in prose by the French playwright Molière. It was first performed on September 9, 1668, in the theatre of the Palais-Royal in Paris.

The miser of the title is called Harpagon, a name adapted from the Latin harpago, meaning a hook or grappling iron. He is obsessed with the wealth he has amassed and always ready to save expenses. Now a widower, he has a son, Cléante, and a daughter, Élise. Although he is over seventy, he is attempting to arrange a marriage between himself and an attractive young woman, Mariane. She and Cléante are already devoted to each other, however, and the son attempts to procure a loan to help her and her sick mother, who are impoverished. Élise, Harpagon's daughter, is the beloved of Valère, but her father hopes to marry her to a wealthy man of his choosing, Seigneur Anselme.

Jean-Baptiste Poquelin, known by his stage name Molière (1622–1673), was a French playwright and actor who is considered to be one of the greatest masters of comedy in Western literature. Among Molière's best-known works are The Misanthrope, The School for Wives, Tartuffe, The Miser, The Imaginary Invalid, and The Bourgeois Gentleman.
