William Douglas Lee was an American architect and designer in the early 20th century whose career focused on designing large Neoclassic, Gothic Revival, Renaissance Revival, and Beaux-Arts style manufacturing buildings in Downtown Los Angeles, as well as other historically notable works such as the Chateau Marmont and the El Royale apartments.

The Chateau Marmont is a hotel located at 8221 Sunset Boulevard in Los Angeles, California. The hotel was designed by architects Arnold A. Weitzman and William Douglas Lee and completed in 1929. It was modeled loosely after the Château d'Amboise, a royal retreat in France's Loire Valley.
