Château Rauzan-Ségla, or Château Rausan-Ségla, is a winery in the Margaux appellation of the Bordeaux region of France. Château Rauzan-Ségla is also the name of the red wine produced by this property. The wine produced here was classified as one of fifteen Deuxièmes Crus (Second Growths) in the original Bordeaux Wine Official Classification of 1855. The alternate name "Rausan-Ségla" was also frequently used until 1994 when the original "Rauzan-Ségla" again became the official name.
It was created through the partition of the former Château Rauzan.
