Château Le Pin, or simply Le Pin, is an unclassed Bordeaux wine from the appellation Pomerol. The unusually small estate is located on the Right Bank of France's Gironde estuary in the commune of Pomerol near the hamlet of Catusseau, and its wine is periodically one of the world's most expensive red wines.

Madame Laubie, whose family had owned the plot since 1924 sold the vineyard in 1979 to the Belgian Thienpont family for 1 million francs. The vineyards were developed by Marcel and Gérard Thienpont (of Vieux Château Certan) on less than 2 hectares,and the wine was produced by microcuvée from a farmhouse basement.

The property was given the name Le Pin by the Thienponts from a solitary pine tree that grows near the winery.

Château Le Pin is considered by some a predecessor of the "garage wines", although this idea is rejected by many, including by the proprietors, on the basis of the merits of the terroir, and the absence of extreme measures to compensate for mediocre grapes.

Occasionally the most expensive wine in the world, continually receiving high wine ratings from wine critics and produced in extremely small numbers, Le Pin bottles are a constant presence on the wine auction market
