Oliver Scott Sykes (born 20 November 1986) is a British singer, songwriter and record producer, best known as the lead vocalist and primary lyricist of the rock band Bring Me the Horizon.

[5] He also played in the mock hip-hop band "Womb 2 Da Tomb" with his brother Tom Sykes and fellow Bring Me the Horizon member Matt Nicholls,[6] and in metal band "Purple Curto" with Neil Whiteley, as the drummer/vocalist under the pseudonym "Olisaurus", which he would later use when releasing solo material.

[8] Sykes has been featured in songs for the bands You Me at Six's "Bite My Tongue",[17] Architects' "Even If You Win, You're Still a Rat", Admiral's Arms' "Dawn of the New Age" and Deez Nuts' "If You Don't Know, You Know Now".

[18] In 2017, Sykes featured as guest vocalist in the song "Silence Speaks" with English metalcore band While She Sleeps.

[19] Sykes was briefly featured in the music video for Charli XCX's song "Boys" along with other artists such as Brendon Urie, Denzel Curry, Charlie Puth and Stormzy.

[24] On 1 February 2013, Sykes launched a Kickstarter project to fund a graphic novel created by him and Drop Dead Clothing artist Ben Ashton-Bell, entitled Raised by Raptors.

[29] In 2006, when asked about the lyrics of Count Your Blessings, as they had been criticised for their content fixated on heartbreak or other themes that were called "shallow and meaningless", he responded "My life's never been that bad so I've not got that much to talk about".

[30] The main character of the French feature film A Taste of Ink is an admirer of Oliver Sykes and Bring Me the Horizon.

[32] Since the age of 12, Sykes has suffered from a form of night terrors known as sleep paralysis, which is the inability to move or speak while falling asleep, or upon waking.

He went on to become one of the faces for PETA, eventually designing charity T-shirts with the slogan "Meat Sucks" via his Drop Dead Clothing line.

"[39][40] On 12 July 2015 in Tuscany, Italy, Sykes married model and tattoo artist Hannah Pixie Snowdon.

[46] In March 2021, Sykes shared a photo on Instagram confirming he stayed in Brazil with his wife for the entirety of the COVID-19 pandemic to that point, that he had acquired a CPF number, [47] and had bought a house in the city of Taubaté, countryside of the state of São Paulo, where he was living with her.

[48] In March 2023, Sykes got his Brazilian National Migration Registry card as a permanent resident of the country.

[54] The videos were uploaded to YouTube, leading to outrage from many Bring Me the Horizon fans, and resulting in hate mail and death threats being sent to Carter.

"[55] In June 2013, Sykes and Bring Me the Horizon were sued by the parents of a 12-year-old girl due to injuries received in the mosh pit while watching the band's performance during the Warped Tour 2013.

This led to Sykes announcing via Twitter that legally he was no longer able to start any form of moshing activities during his concerts.
