Château Haut-Marbuzet (French pronunciation: [ʃɑto o maʁbyzɛ]) is a Bordeaux wine estate in the Saint-Estèphe appellation area of the Haut-Médoc.

The high proportion of merlot, rather unusual in traditional blendings, as well as a long maturing in new oak barrels, greatly contribute to the mellowness of the wine.

[6] Often described as exotic or opulent, Haut-Marbuzet wines develop a suppleness and an individual expressive character that are unusual in the normally austere style of Saint-Estèphe.

Jay McInerney describes the wine's relationship to its neighbors as "if a bikini-clad Juliette Binoche crashed a meeting of the French Academy.

"[7] A second wine is produced from the vines under 12 years old, under the label Château MacCarthy,[5][8] which bears the name of the Irish Jacobite family who created the vineyard.
