Henry McCullough (born Henry Campbell Liken McCullough, 21 July 1943, Portstewart, Northern Ireland) is an Irish guitarist, vocalist and songwriter, who has played guitar in such bands as Sweeney's Men, Spooky Tooth, Paul McCartney & Wings, and The Grease Band. He turned up in many different places as sideman or a performer in his own right. In 2008, he recorded Poor Man's Moon, featuring the single, "Too Late to Worry."

McCullough first came to prominence in the early 1960s as the teenage lead guitarist with The Skyrockets showband from Enniskillen. In 1964, with three other members of The Skyrockets, he left and formed a new showband fronted by South African born vocalist Gene Chetty, which they named Gene and The Gents.

In 1967 McCullough moved to Belfast where he joined Chris Stewart (bass), Ernie Graham (vocals) and Dave Lutton (drums) to form the psychedelic band The People. Later that year the band moved to London and were signed by Chas Chandler's management team, who changed the group’s name to Éire Apparent. Under Chandler's guidance, despite only having one single released, they toured with groups such as Pink Floyd, Soft Machine, The Move and The Jimi Hendrix Experience. Things went well until, in Vancouver, Canada in mid February 1968, McCullough was busted for possession of marijuana and sent back to Ireland (officially because of 'visa problems'), and Mick Cox flew out to take his place in the band.
