Mourvèdre, Monastrell, or Mataro is a variety of wine grape grown around the world. It is Spain's second-most widely planted red wine grape after Garnacha Tinta and was once Provence's most popular grape.

Mourvèdre is known by various names: in Spain as Monastrell (or occasionally Morastell or Morrastel), in the Americas and Australia as Mataro (or occasionally Esparte), and in France sometimes as Balzac.

Its names probably come from the towns of Mataró in Cataluña and Murviedro near Valencia. In certain regions of France it is also still known as Estrangle-Chien ("dog strangler").

The grape requires a hot climate to ripen, and is thus only found in the very south of France. Even in Spain it is only grown in significant quantities in the southern half of the country. In hot years, it is capable of producing high-alcohol wines with a high level of tannin, but its producers have so far been unable to create world-class wines. Nonetheless, Mourvèdre is more than capable of generating vin de table with a great degree of finesse, especially in blends with Syrah and Grenache.

Its taste varies greatly according to area, but often has a wild, gamey or earthy flavour, with soft fruit flavours of blackberry.
