Mazoyères-Chambertin is an Appellation d'origine contrôlée (AOC) and Grand Cru vineyard for red wine in the Côte de Nuits subregion of Burgundy, with Pinot noir as the main grape variety. Mazoyères-Chambertin is located within the commune of Gevrey-Chambertin. It is situated below (to the east of) the Route des Grands Crus. It borders on Latricières-Chambertin and the Gevrey-Chambertin Premier Cru aux Combottes in the west, Charmes-Chambertin in the north, Gevrey-Chambertin village level vineyards in the east, and Morey-Saint-Denis Premier Cru vineyards in the south. The AOC was created in 1937.
A peculiarity of Mazoyères-Chambertin is that the appellations Charmes-Chambertin (of the neighbouring Grand Cru vineyard) may be used interchangeably with that of Mazoyères-Chambertin. As Charmes-Chambertin is the more popular to use, relatively little wine is bottled as Mazoyères-Chambertin, which is only around 10 per cent of the production.
Another grand cru vineyard in Gevrey Chambertin with a similar name, but no other connection is Mazis-Chambertin which is also known as Mazy-Chambertin.
