Nick Walker (born 1969)[1] is a British graffiti artist originating from Bristol, England. His paintings often feature a bowler-hatted gentleman 'vandal'.[2]

He is credited with being part of the stencil graffiti movement that Robert Del Naja started in the 1980s, which was also an influence on Banksy.

Walker recreated the graffiti'd streets of New York City for Stanley Kubrick's 1999 film, Eyes Wide Shut.[2] His work was included in a video by The Black Eyed Peas.[2]

​

Walker was a main participant in the 2011 See No Evil event in Bristol, where he painted "perhaps the most striking piece at the event",[4] one of his bowler-hatted gentleman on the side of a tower block in Nelson Street.

Walker was the first artist-in-residence of the Quin Arts program at the Quin Hotel in New York City.[5] Walker created 15 original pieces on-site for the Quin’s permanent collection during his residency in 2013, shortly following the hotel's opening.[6] In February 2016, Walker revisited the Quin to show both historic images, as well as a new vocabulary of abstraction. This solo exhibit, curated by DK Johnston, presented 25 original works and opened the hotel’s Quin Arts program for the 2016 season.[7] In November 2016, Walker joined a cohort of fellow former Quin Arts artists-in-residence in using a D’Angelico Guitar as their “canvas,” for an artist salon. His design featured curvilinear numbers resembling musical notes.[8]

Walker still lives in Bristol
