The Walt Disney Concert Hall at 111 South Grand Avenue in downtown Los Angeles, California, is the fourth hall of the Los Angeles Music Center and was designed by Frank Gehry. It was opened on October 23, 2003. Bounded by Hope Street, Grand Avenue, and 1st and 2nd streets, it seats 2,265 people and serves, among other purposes, as the home of the Los Angeles Philharmonic orchestra and the Los Angeles Master Chorale. The hall is a compromise between a vineyard-style seating configuration, like the Berliner Philharmonie by Hans Scharoun, and a classical shoebox design like the Vienna Musikverein or the Boston Symphony Hall.

Lillian Disney made an initial gift of $50 million in 1987 to build a performance venue as a gift to the people of Los Angeles and a tribute to Walt Disney's devotion to the arts and to the city. Both Gehry's architecture and the acoustics of the concert hall, designed by Minoru Nagata, the final completion supervised by Nagata's assistant and protege Yasuhisa Toyota, have been praised, in contrast to its predecessor, the Dorothy Chandler Pavilion.

The Walt Disney Concert Hall was designed by world-renowned architect Frank Gehry. Despite being a well-accomplished architect at the time of design, Gehry found himself an unlikely candidate for the job when the Disney family was looking for the hall's designer. Even with the location of the Walt Disney Concert Hall set to be in his hometown of Los Angeles, California, Gehry, when discussing his thoughts at the time the architect was selected, said, "it was the least likely thing that I thought would ever happen to me in my life". Gehry's opinion was supported by the representative of the Disney family. Gehry says he was told, "that under no circumstances would Walt Disney's name be on any buildings that I design". Much of this doubt came from Gehry's reputation for relying on the use of cheap materials in his architecture that were used in unconventional ways. With the Walt Disney Concert Hall being a project that demanded a high budget and an elegant style, Gehry did not seem like the right candidate for the job. However, Gehry's determination landed him the job of designing the hall, as he produced a design that caught the eye of Walt Disney's widow, Lillian. His design included some of the elements of the deconstructivist architecture that he was known for, while still producing an elegant structure.

The project was initiated in 1987, when Lillian Disney, widow of Walt Disney, donated $50 million. Frank Gehry delivered completed designs in 1991. Construction of the underground parking garage began in 1992 and was completed in 1996. The garage cost had been $110 million, and was paid for by Los Angeles County, which sold bonds to provide the garage under the site of the planned hall. Construction of the concert hall itself stalled from 1994 to 1996 due to lack of fundraising. Additional funds were required since the construction cost of the final project far exceeded the original budget. Plans were revised, and in a cost-saving move the originally designed stone exterior was replaced with a less costly stainless steel skin. The needed fundraising restarted in earnest in 1996, headed by Eli Broad and then-mayor Richard Riordan. Groundbreaking for the hall was held in December 1999. Delay in the project completion caused many financial problems for the county of LA. The County expected to repay the garage debts by revenue coming from the Disney Hall parking users.

Due to the mathematical complexity of Gehry's innovative design, he relied on computer software to produce his design in a way that could be completed by contractors. The technology, called CATIA (computer-aided three-dimensional interactive application) is typically used in the design process for French fighter jets, but its mathematical ability aided Gehry in his process of designing the Walt Disney Concert Hall. Perhaps it is the angle-based design of the concert hall that required the use of CATIA, which can be seen on the exterior of the building. For example, the box columns on the north side of the Walt Disney Concert Hall are tilted forward at seventeen degrees. The angular design was used by Gehry to "symbolize musical movement and the motion of Los Angeles".

Upon completion in 2003, the project cost an estimated $274 million; the parking garage alone cost $110 million. The remainder of the total cost was paid by private donations, of which the Disney family's contribution was estimated at $84.5 million with another $25 million from The Walt Disney Company. By comparison, the three existing halls of the Music Center cost $35 million in the 1960s (about $330 million in 2021 dollars).

As construction finished in the spring of 2003, the Philharmonic postponed its grand opening until the fall and used the summer to let the orchestra and Master Chorale adjust to the new hall. Performers and critics agreed that it was well worth this extra time taken by the time the hall opened to the public. During the summer rehearsals a few hundred VIPs were invited to sit in including donors, board members and journalists. Writing about these rehearsals, Los Angeles Times music critic Mark Swed wrote the following account:

When the orchestra finally got its next [practice] in Disney, it was to rehearse Ravel's lusciously orchestrated ballet, Daphnis and Chloé. ... This time, the hall miraculously came to life. Earlier, the orchestra's sound, wonderful as it was, had felt confined to the stage. Now a new sonic dimension had been added, and every square inch of air in Disney vibrated merrily. Toyota says that he had never experienced such an acoustical difference between a first and second rehearsal in any of the halls he designed in his native Japan. Salonen could hardly believe his ears. To his amazement, he discovered that there were wrong notes in the printed parts of the Ravel that sit on the players' stands. The orchestra has owned these scores for decades, but in the Chandler no conductor had ever heard the inner details well enough to notice the errors.
