Château Montrose is a winery in the Saint-Estèphe appellation of the Bordeaux region of France. The wine produced here was classified as one of fourteen Deuxièmes Crus (Second Growths) in the original Bordeaux Wine Official Classification of 1855.

The vineyard is in Saint-Estèphe, the northernmost of the great Médoc communes. The soil in Montrose's 168 acres (0.68 km2) consists of gravel and black sand with a subsoil of clay and marl. They are planted with 65% Cabernet Sauvignon, 25% Merlot and 10% Cabernet Franc.

Château Montrose produces two red wines: its eponymous grand vin, and a second wine named La Dame de Montrose. The 1970 vintage was placed third among the ten California and French red wines at the historic Judgment of Paris wine competition, which was won by the Americans.

Montrose wines tend to be deeply tannic and during excellent vintages can take up to 20 years to mature.

The 1990, 2009 and 2010 vintages were rated 100 points by Robert M. Parker, Jr.
