The Pellissier Building and adjoining Wiltern Theatre is a 12-story, 155-foot (47 m) Art Deco landmark at the corner of Wilshire Boulevard and Western Avenue in Los Angeles, California. The entire complex is commonly referred to as the Wiltern Center. Clad in a blue-green glazed architectural terra-cotta tile and situated diagonal to the street corner, the complex is considered one of the finest examples of Art Deco architecture in the United States. The Wiltern building is owned privately, and the Wiltern Theatre is operated by Live Nation's Los Angeles division.

Originally built in 1931, the Wiltern was designed by architect Stiles O. Clements of Morgan, Walls & Clements, the city's oldest architectural firm. The Wiltern Theatre was originally designed as a vaudeville theater and initially opened as the Warner Brothers Western Theater, the flagship for the theater chain. The building and theater were built by the William Simpson Construction Company. After closing a year later, the theater reopened in the mid-1930s and was renamed the Wiltern Theatre for the major intersection which it faces (Wilshire Boulevard and Western Avenue). In 1956, the building and theater were sold to the Franklin Life Insurance Company of Springfield, Illinois. The Los Angeles chapter of the American Theater Organ Enthusiasts worked to restore the theater's 37-rank Kimball pipe organ—reputed to be the largest one in Los Angeles at the time—and held recitals there through the late 1960s and into the mid-1970s. However, the owners ignored the landmark building, and by the late 1970s, the Wiltern had fallen into disrepair. Only the intervention of a group of local preservationists saved the complex from being demolished on two occasions in the late 1970s, when the owners filed for demolition permits.
