Château Giscours is a winery in the Margaux appellation of the Bordeaux region of France, in the commune of Labarde. The wine produced here was classified as one of fourteen Troisièmes Crus in the Bordeaux Wine Official Classification of 1855.

The Margaux appellation encompasses the village of Margaux and the neighbouring villages of Arsac, Labarde, Soussans and Cantenac. Being the most southerly of the Médoc's appellations, it has the thinnest soil in the region with the highest proportion of gravel that allows the soil to drain very well. The wine from this area are very susceptible to weather effects during the growing season. Encountering all seasons with adequate irrigation, relatively good rainfall and good amount of sunlight, the crop yields a bountiful harvest year-on-year. The winery takes pride and value that captures the essence that reflects their unique brand.
