PH Live is a mid-sized auditorium in the Planet Hollywood Las Vegas hotel and casino on the Las Vegas Strip in Paradise, Nevada, United States. The venue hosts events including charity benefits, concerts and award shows including beauty pageants such as Miss Universe, Miss USA and Miss Teen USA.

While this location was known as the Aladdin Hotel, the owners decided to create a performing arts center to replace the mildly used golf course. Planning began in 1969, with concepts showing the venue as a separate building. In 1972, the hotel was sold to Sam Diamond, Peter Wevve, Sorkis Wevve and Richard Daly. The theater opened on July 2, 1976 (America's bicentennial weekend), with Neil Diamond, who was paid $750,000 for five sold-out shows. During the 1970s and 1980s, the auditorium became a staple on the Strip for many rock and roll acts. In September 1977, Frank Zappa's road manager was found dead of self-inflicted razor-blade wounds after a performance at the venue. In November 1997, at the final performance at the venue before it closed for renovations, Mötley Crüe invited fans onto the stage, resulting in a flying chairs and signs ripped from walls. Guitarist Mick Mars was knocked out in the melee. Tommy Lee invited women to flash a video camera. In 1998, the original Aladdin Hotel was imploded. During the renovation, the center's original structure was removed, incorporating the venue into the casino area of the hotel. In 2000, the venue reopened with a performance by Enrique Iglesias, with a capacity decrease to 7,000. Due to new competition from the MGM Grand Garden Arena and Mandalay Bay Events Center, the venue was used infrequently by music acts.
