Auxerrois blanc () or Auxerrois Blanc de Laquenexy is a white wine grape that is important in Alsace, and is also grown in Germany and Luxembourg. It is a full sibling of Chardonnay that is often blended with the similar Pinot blanc.

History
Auxerrois blanc is thought to have originated in Lorraine, rather than near Auxerre in the Yonne. Recent DNA fingerprinting suggests that it is a cross between Gouais blanc and Pinot, the same ancestry as Chardonnay. The name Auxerrois blanc has actually been used as a synonym for Chardonnay in the Moselle region in France, which explains why there is also a longer name (Auxerrois Blanc de Laquenexy) for the grape variety.
