The Pacific Design Center, or PDC, is a 1,600,000-square-foot (150,000 m²) multi-use facility for the design community in West Hollywood, California. One of the buildings is often described as the Blue Whale because of its large size relative to surrounding buildings and its brilliant blue glass cladding.

The PDC houses the West Coast's top decorating and furniture market, with showrooms, public and private spaces and used to host a branch of the Museum of Contemporary Art (MOCA). The Center has 100 showrooms which display and sell 2,200 interior product lines to professional interior designers, architects, facility managers, decorators and dealers.^[1]

The Pacific Design Center hosts many screenings, exhibitions, lectures, meetings, special events and receptions for the design, entertainment and arts communities. The annual Elton John AIDS Foundation Academy Award Party has traditionally been held at the PDC. The party is one of the longest running and best known of the post-Oscar parties as well as being a multimillion-dollar fundraiser for the foundation.^[2]

The interior of one floor of the Blue Whale, and the escalators of the same building, are used extensively as the underground workshops for the Westworld TV series.

Designed by Argentine architect César Pelli, the 14-acre (57,000 m²) campus opened in 1975, with the 750,000-square-foot (70,000 m²) Center Blue. Architect Norma Merrick Sklarek also contributed to the architectural design of the building.^[3] Center Green opened in 1988, adding 450,000 square feet (42,000 m²). The final phase of the plan, Center Red, opened in 2013 with an additional 400,000 square feet (37,000 m²).^[4]
