Chateau Saint-Pierre is a Fourth Growth (4ème Grand Cru Classé) red Bordeaux wine from the prestigious Saint-Julien appellation in the Médoc region of Bordeaux, France. It is the smallest classified estate in the appellation, producing approximately 6,000 cases annually from just 17 hectares of vineyard.

The wine is a classic Médoc blend of approximately 75% Cabernet Sauvignon, 15% Merlot, and 10% Cabernet Franc, crafted from vines averaging 50 years of age planted on gravel, sand, and clay soils. Each vintage is aged for 14–16 months in approximately 60% new French oak barrels, with malolactic fermentation conducted in barrel for added complexity and texture.

Owned by the Martin family since 1982, Chateau Saint-Pierre has undergone significant investment since 2005 and a major facility renovation in 2016, establishing it as one of Saint-Julien's most consistent overperformers relative to its classification. The estate was among the first in the Médoc to use satellite imagery to guide harvest decisions. Best served at 15.5°C (60°F), this wine pairs beautifully with beef, lamb, duck, game, roasted meats, and aged cheeses. It offers its best drinking between 10 and 25 years of age after vintage; younger vintages benefit from 2–3 hours of decanting.
