Chester Charles Bennington (March 20, 1976 – July 20, 2017) was an American singer and songwriter known as the lead singer for the rock band Linkin Park. He also served as the frontman for Dead by Sunrise and Stone Temple Pilots.

Bennington first gained prominence as a vocalist following the release of Linkin Park's debut album, Hybrid Theory, in 2000, which became a commercial success. The album was certified Diamond by the Recording Industry Association of America in 2005, making it the best-selling debut album of the decade, as well as one of the few albums ever to hit that many sales. Linkin Park's following studio albums, from Meteora (2003) to One More Light (2017), continued the band's success. Linkin Park has sold over 100 million records worldwide

Bennington formed his own band, Dead by Sunrise, as a side project in 2005. The band's debut album, Out of Ashes, was released on October 13, 2009. He worked on new material with Stone Temple Pilots in 2013 to release the EP High Rise on October 8, 2013, via their own record label, Play Pen. He was widely regarded as one of the top rock vocalists of the 2000s. Hit Parader magazine placed him at #46 on their list of the "100 Metal Vocalists of All Time". He also appeared in cameo roles in several films, including Crank, Crank: High Voltage and Saw 3D.

On July 20, 2017, Bennington was found dead in his home in Palos Verdes Estates, California, from suicide by hanging.
