The Los Angeles Philharmonic (LA Phil, LAP, or LAPO) is an American orchestra based in Los Angeles, California, United States. It has a regular season of concerts from October through June at the Walt Disney Concert Hall, and a summer season at the Hollywood Bowl from July through September. Gustavo Dudamel is the current Music Director, and Esa-Pekka Salonen is Conductor Laureate. Deborah Borda is the current President and CEO.

Music critics have described the orchestra as the most "contemporary minded", "forward thinking", "talked about and innovative", "venturesome and admired" orchestra in America. According to Salonen, "We are interested in the future. We are not trying to re-create the glories of the past, like so many other symphony orchestras." “Especially since we moved into the new hall,” continues Borda, “our intention has been to integrate 21st-century music into the orchestra’s everyday activity.” Since the opening of the Walt Disney Concert Hall on October 23, 2003, the Los Angeles Philharmonic has presented 57 World premieres, 1 North American premiere, 26 U.S. premieres and has commissioned or co-commissioned 63 new works.
