Shoreline Amphitheatre is an outdoor amphitheater located in Mountain View, California, in the San Francisco Bay Area. The venue has a capacity of 22,500, with 6,500 reserved seats and 16,000 general admission on the lawn. When the parking lot is utilized for festival stages, the total capacity of the venue can reach 30,000. The venue has hosted popular music festivals such as Lollapalooza and Ozzfest, and also developer conferences such as the Google I/O.

The amphitheatre was built in 1985–1986 by the city of Mountain View, in cooperation with local promoter Bill Graham, as part of the Shoreline Park project. Graham designed the amphitheatre to resemble The Grateful Dead's "steal your face" logo when seen from overhead. The premiere season was during the summer of 1986. It was planned to open with a concert by The Grateful Dead, but they cancelled due to Jerry Garcia's ill health. The first performance at the amphitheater was comedienne Roseanne Barr, opening for Julio Iglesias on June 29, 1986. The Grateful Dead played their first concert at Shoreline in early October 1987, and played another thirty-eight times; with their final appearance on June 4, 1995.. Jerry Garcia played a further three shows as part of the Jerry Garcia Band. On February 2, 1998, a major El Niño storm caused a power outage that disabled the pumps that normally drain rainfall from the amphitheater. Combined with torrential rains, this caused water to fill the bottom of the amphitheater bowl to a depth of more than 15 feet, ruining the stage and much of the backstage infrastructure and causing $2.5 million in damage. The damage was repaired by May 17 when the season's opening concert took place. The amphitheatre was the site of two homicides. In 2015, a man was fatally shot backstage during a Wiz Khalifa concert.
