Krug Champagne is a Champagne house founded by Joseph Krug in 1843. It is based principally in Reims, the main city in France's Champagne region and is one of the famous Champagne houses that formed part of the Grandes marques. Today the house is majority owned by the multinational conglomerate Moët Hennessy – Louis Vuitton (LVMH) whose portfolio includes other well known wine brands such as Moët & Chandon, Veuve Clicquot, Château d'Yquem and Ruinart. Despite LVMH's majority ownership, the Krug family is still actively involved in all the key decisions of the house but does not manage the day-to-day operations.

Moët & Chandon's Dom Pérignon is often compared to Krug, the latter being described as a "more intellectual wine" by Jancis Robinson.
