Chassagne-Montrachet is a village appellation in the Côte de Beaune subregion of Burgundy, France. Located in the southern portion of the Côte de Beaune, the commune shares its eastern border with Puligny-Montrachet and sits adjacent to the famous Montrachet vineyard. The appellation was established in 1937 and encompasses both village-level and premier cru vineyards across the commune's slopes and valleys.

The appellation's vineyards are planted on limestone and marl soils typical of the Côte de Beaune, with various exposures and elevations that create distinct microclimates. Chardonnay dominates the plantings and produces the majority of wines, though Pinot Noir is also permitted and cultivated on certain sites. The appellation includes over 50 premier cru climats, each with specific soil compositions and orientations that influence wine character. Traditional Burgundian winemaking methods are employed, with white wines typically fermented and aged in oak barrels.

Chassagne-Montrachet whites display the mineral-driven character associated with Burgundian Chardonnay, often showing citrus and stone fruit flavors with notable chalky minerality. The wines tend to be more structured and austere in youth compared to neighboring Puligny-Montrachet, developing complexity and richness with age. Red wines from the appellation are less common but offer typical Pinot Noir characteristics with earth and red fruit notes, generally lighter in style than those from appellations further north in the Côte de Beaune.
