Page Nye Hamilton (born May 18, 1960) is an American guitarist, singer, songwriter and record producer who founded the American heavy metal band Helmet in 1989. In the 1990s, Helmet and Hamilton were forerunners of alternative metal with the albums Meantime (1992) and Betty (1994) and are considered one of the most influential metal bands of all time. Although he is mainly known for his work in heavy metal and post-hardcore music, Hamilton also earned an undergraduate degree from the University of Oregon and later earned a Master's degree in jazz guitar from the Manhattan School of Music. Hamilton also has connections to avant-garde music and film soundtrack composition.

Hamilton was born on May 18, 1960, in Portland, Oregon, and raised in Medford, Oregon. He studied guitar at the University of Oregon before moving to New York to study jazz guitar at the Manhattan School of Music. While there he played in avant-garde composer Glenn Branca's guitar orchestra, performing the composer's Symphony No.6 (Devil Choirs at the Gates of Heaven), and joined noise rock band Band of Susans, performing on their Love Agenda album and Peel Sessions, before finally forming his own group, Helmet.

Helmet initially signed to Amphetamine Reptile Records, releasing a number of 7" singles and one album, 1990's Strap It On. The band then signed to Interscope Records, releasing Meantime (1992), Betty (1994) and Aftertaste (1997). After a seven-year hiatus, the band returned with Size Matters (2004). A year after the release of Size Matters, they left Interscope, and the band released the albums Monochrome (2006), Seeing Eye Dog (2010), Dead to the World (2016) and Left (2023).

Meantime was the band's principal commercial success, being certified gold by the Recording Industry Association of America. The album was well received by music critics and is seen as an influential metal record and earning a Grammy nomination in the Best Metal Performance category for 1993.

Since 2004, Hamilton has been the only founding member left in Helmet, and after the departure of guitarist Chris Traynor in 2006, he has been the only member to have been involved with Helmet during its original run in the 1990s. Hamilton has said that he hopes to keep playing with Helmet until he is "physically incapable".

Following Helmet's temporary dissolution in the late 1990s, Hamilton formed another rock band, Gandhi, with former Liege Lord guitarist Anthony Truglio, John Andrews (guitar), Christian Bongers (bass), and Matt Flynn (later the drummer for Maroon 5). Though the band did not release any music officially, several demo songs were leaked. Many of these were later recorded for the Size Matters and Monochrome releases by Helmet.

While still active with Helmet, Hamilton embarked on a career composing and performing music for film, working on movies including Heat, Titus, In Dreams, Catwoman, and Chicago Cab. Helmet also contributed to a number of movie soundtracks, including The Crow, Feeling Minnesota, Johnny Mnemonic, Judgment Night, Saw 3, Underworld, and appearing in The Jerky Boys: The Movie (performing a cover of the Black Sabbath song "Symptom of the Universe").

Hamilton has also worked as a record producer, most notably producing the album Distort Yourself by former Bush singer Gavin Rossdale's band Institute. He has also produced albums for the bands Bullets and Octane (In the Mouth of the Young), Classic Case (Losing at Life), and Totimoshi.
