Blaufränkisch (German for blue Frankish) is a dark-skinned variety of grape used for red wine. Blaufränkisch, which is a late-ripening variety, produces red wines which are typically rich in tannin and may exhibit a pronounced spicy character.

The grape is grown across Central Europe, including Austria, Czech Republic (in particular southern Moravia where it is known as Frankovka), Germany and Washington State (where it is known as Lemberger, or Blauer Limberger), Slovakia (where it is known as "Frankovka modrá"), Croatia ("frankovka") and Slovenia (known as "modra frankinja"). In Hungary the grape is called Kékfrankos (also lit. blue Frankish) and is grown in a number of wine regions including Sopron, Villány, Szekszárd, and Eger (where it is a major ingredient in the famous red wine blend known as Egri Bikavér (lit. Bull's Blood) having largely replaced the Kadarka grape). It has been called "the Pinot Noir of the East" because of its spread and reputation in Eastern Europe.

DNA profiling has shown that Blaufränkisch is a cross between Gouais blanc (Weißer Heunisch) and an unidentified Frankish variety. One of the candidates for the Frankish parent is Blauer Silvaner.

For a long time before the application of DNA analysis, Blaufränkisch was erroneously thought to be a clone of the Gamay grape variety, due to certain similarities in morphology and possibly due to its name Gamé in Bulgaria.

The German name Lemberger derives from the fact that it was imported to Germany in the 19th century from Lemberg in Lower Styria in present-day Slovenia and then in the Austro-Hungarian Empire. An 1877 export of Lembergerreben to Germany has been recorded. The almost identical name Limberger refers to Limburg at Maissau in Lower Austria, where in the late 19th century "ungrafted Limberg Blaufränkisch vines" (wurzelechte Limberger Blaufränkisch-Reben) were offered for sale.

Washington State is one of the few major wine regions in North America to have significant plantings of Lemberger. Grapes of this Washington wine mostly grow in Yakima Valley, but also at the Olympic Peninsula. Small amounts of Lemberger are also grown in New York State, Colorado, Ohio, and Virginia.
