No, Hyatt does not own Ritz-Carlton. As of 2026, The Ritz-Carlton Hotel Company is a wholly-owned subsidiary of Marriott International. Marriott acquired the brand in 1995 and has since expanded it into one of its top-tier "Luxury" brands, alongside St. Regis and JW Marriott. Hyatt Hotels Corporation, on the other hand, is a direct competitor to Marriott and manages its own portfolio of luxury brands, such as Park Hyatt, Andaz, and the Grand Hyatt. While both companies have undergone significant consolidation and acquisitions over the last decade—with Marriott buying Starwood and Hyatt acquiring brands like Thompson Hotels and Apple Leisure Group—the two remains entirely separate corporate entities. For travelers, this means you cannot use Hyatt "World of Hyatt" points for a stay at a Ritz-Carlton; you must use Marriott Bonvoy points to book a stay at any Ritz-Carlton property worldwide.
