W Hotels is an American lifestyle hotel chain owned by Marriott International that is marketed towards a younger age group. The chain was launched in 1998 with W New York, a conversion of the former Doral Inn hotel on Lexington Avenue in Manhattan.

The hotel quickly became popular as a New York City nightclub. Identifying a gap in the market, Barry Sternlicht, CEO of Starwood Hotels 1995–2005, created the brand that popularized the lifestyle hotel concept of focusing on fashion and design.

Marriott is the largest hotel chain in the world, with 30 brands and 8,000 properties in 131 countries and territories. Of these properties, 2,149 are operated by Marriott, and 5,493 are operated by others pursuant to franchise agreements. The company also operates 20 hotel reservation centers.
