LVMH is the parent company of Louis Vuitton, Christian Dior, and Moët & Chandon.
LVMH is short for Moët Hennessy Louis Vuitton. The group was formed in 1987 through the merger of fashion house Louis Vuitton with wine and spirits producer Moët Hennessy. It grew into the world's largest luxury-goods company by assembling brands across fashion, jewelry, watches, perfumes, cosmetics, wines, and spirits.
Its portfolio includes maisons with distinct histories and identities rather than one standardized product line. Louis Vuitton, Christian Dior, and Moët & Chandon therefore remain separate consumer brands even though they share a corporate parent.
LVMH is often confused with Kering, another major French luxury group. Kering owns brands such as Gucci and Saint Laurent, while LVMH owns the brands named in this question.
