Veuve Clicquot Ponsardin (French pronunciation: [vøv kliko pɔ̃saʁdɛ̃]) is both a champagne house in Reims, France, and a brand of premium champagne. Founded in 1772 by Philippe Clicquot-Muiron, Veuve Clicquot played an important role in establishing champagne as a favored drink of haute bourgeoisie and nobility throughout Europe. The 1811 comet vintage of Veuve Clicquot is theorized to have been the first truly "modern" Champagne due to the advancements in the méthode champenoise which Veuve Clicquot pioneered through the technique of remuage.

In 1772, Philippe Clicuot-Muiron established the original enterprise which in time became the house of Veuve Clicquot. His son, François Clicquot, married Barbe-Nicole Ponsardin in 1798 and died in 1805, leaving his widow (veuve in French) in control of a company variously involved in banking, wool trading, and Champagne production. Under Madame Clicquot's guidance the firm focused entirely on the latter, to great success.

During the Napoleonic Wars, Madame Clicquot made strides in establishing her wine in royal courts throughout Europe, notably that of Imperial Russia. By the time she died in 1866 Veuve Clicquot had become both a substantial Champagne house and a respected brand. Easily recognised by its distinctive bright yellow labels, the wine holds a royal warrant of Queen Elizabeth II of the United Kingdom.
