Auxerrois blanc (pronounced [o.sɛ.ʁwa blɑ̃]) or Auxerrois Blanc de Laquenexy is a white wine grape prevalent in the French region of Alsace, and is also grown in neighbouring Germany and Luxembourg.

Recent DNA fingerprinting suggests that it is a cross between Gouais blanc and Pinot, the same ancestry as Chardonnay.

France's 1,950 hectares (4,800 acres) of Auxerrois blanc are mostly in Alsace, with some in the Côtes de Toul of Lorraine.

Free Run Cellars in Berrien county, Michigan (southwest MI), is now producing it (2018).

Island View Orchard planted Auxerrois on Old Mission Peninsula in Traverse City, Michigan in 2016, and it is made at Left Foot Charley.

In Canada, Auxerrois is grown on Vancouver Island in British Columbia where Alderlea Vineyards blends it with Ortega (Another cold climate grape, grown in Dragonfly Hill Vineyard[3]) and Pinot Gris.
