Catalan wines are those that are produced in the wine region of Catalonia. Occasionally, the appellation is applied to some French wine made in the Catalan region of Roussillon because of the transfer of French territories that currently are part of Spain. The city of Barcelona is the capital of Catalonia and despite not being in a wine region (although a portion of the Penedès is in the greater comarca of Barcelona) it is the focal point of the Catalan wine industry: a primary consumer market, its port provides export functions and a source of financial resources and investment.

The area has a long winemaking tradition and was the birthplace of the sparkling wine Cava, invented in the early 1870s in Sant Sadurní d'Anoia by Josep Raventos of Codorníu Winery. At the turn of the 20th century, the Catalan wine industry was at the forefront of Spain's emergence as a world leader in quality wine production, being the first Spanish wine region to adopt the use of stainless steel fermentation tanks. The area is also an important cork production region, with output aimed primarily at the region's Cava houses.

Catalunya is a Spanish Denominación de Origen (DO) for wines which was formally recognised in 1999. It was created with the specific purpose of providing commercial support to over 200 wineries (bodegas) that produced quality wine but which were not included in other specific DO’s in Catalonia.

It does not have a specific geographical location but is formed by over 40 km² of individual vineyards which are dispersed all over Catalonia.
