Domaine Arnoux-Lachaux is a red wine producer located in Vosne-Romanée, in Burgundy's Côte de Nuits. The domaine is best known for premium expressions of Pinot Noir from some of the best appellations in Burgundy. Many of the parcels sit adjacent to those of Burgundy superpower Domaine de la Romanée-Conti.

The founders of the estate were Charles Arnoux and Renée Salbreux, and their son Robert took over the estate in 1957. He acquired small plots of vines around Burgundy in both grand and premier cru appellations and, today, the domaine has 14.5 hectares (35 acres) of vines in four grand cru, five premier cru and five village appellations.

In 1987, Florence Arnoux and her husband Pascal Lachaux began to work with her father, Robert, at the domaine – they were in charge of the estate since Robert's death in 1995. The name was changed to Arnoux-Lachaux in 2008 to reflect the current ownership and winemaking is now headed-up by son Charles Lachaux, a vocal supporter of Burgundy doyenne Lalou-Bize Leroy and her wines.

The Arnoux-Lachaux vines in the Côte de Nuits appellations are between 40 and 90 years old, with those of Romanée-Saint-Vivant some of the oldest. Holdings of the domaine include plots in Vosne-Romanée, Clos de Vougeot, Nuits-Saint-Georges, Chambolle-Musigny, Echezeaux and Latricières-Chambertin.

Lachaux uses an organic and biodynamic approach to farming the vines, although currently the domaine is not certified for either.

The wines are vinifed at the domaine's winery in Vosne-Romanée. The wines are aged in French oak and are bottled without being fined nor filtered.
