St. Regis Hotels & Resorts is an American multinational luxury hotel chain, owned and managed by Marriott International.

In 1904, John Jacob Astor built the St. Regis New York as a sister property to his part-owned Waldorf-Astoria Hotel. Exhibiting luxury and technological advance, each room had its own telephone. Ownership changes, a new wing, and restorations occurred over the following decades. In 1966, Sheraton Hotels purchased the property.^[1] After an extensive restoration in 1991, the hotel became the flagship for the Sheraton premier hotels rebranded as the ITT Sheraton Luxury Collection.^[2]

In 1998, Starwood acquired the Sheraton brand,^[3] and created a new St. Regis brand.^[4] In September 2016, Marriott gained the St. Regis chain as part of its acquisition of Starwood.^[5] The brand name cannot be used in the lower mainland of British Columbia, because the name is legally owned by the independent St. Regis Hotel, Vancouver, built in 1913.^[6]

Currently, there are 57 St. Regis-branded hotels around the world with over 10,000 rooms.^[14][11]

In January 2018, SolidBlock created a smart contract and digitized platform for the tokenization of The St. Regis Aspen, which became the first private single asset real estate investment trust (REIT) in the US to issue a Security Token Offering and traded on the blockchain. Through an intensive campaign, $18 million was raised - nearly one-fifth of the equity deal sold through digital tokens to investors worldwide.^[72]
