Gascoigne was born in Dunston, Tyne and Wear on 27 May 1967. His father, John (1946-2018), was a hod carrier, and his mother, Carol, worked in a factory. He was named Paul John Gascoigne in tribute to Paul McCartney and John Lennon of the Beatles. He attended Breckenbeds Junior High School, then the Heathfield Senior High School, both in the Low Fell area of Gateshead.

Having already gained some coaching experience in China, Gascoigne signed for Boston United on 30 July 2004. After being at the club for 11 games he left (partly as a result of the club refusing to let him participate in the reality television show I'm a Celebrity...Get Me Out of Here!) on 5 October, to begin a football coaching course. After leaving Boston, he stated that he was interested in taking over as manager of Scottish side Greenock Morton, but this came to nothing.  In mid-2005 he spent two months as player-coach at the recently founded Portuguese team Algarve United, but he returned to England after a proposed contract never materialised. He was appointed manager of Conference North club Kettering Town on 27 October 2005, and also planned to put in enough money to own one-third of the club to show his commitment. Previous manager Kevin Wilson was appointed as director of football, and Paul Davis was appointed as the club's assistant manager. Bookmakers put odds on Gascoigne being dismissed before Christmas, though he insisted that he was at the club "for the long haul". Attempts to get new sponsors on board were successful, though results on the pitch soon went against Kettering. His tenure lasted just 39 days, and he was dismissed by the club's board on 5 December. The club's owner, Imraan Ladak, blamed Gascoigne's alcohol problems, stating that he drank almost every day he worked. Gascoigne later claimed that the owner had interfered incessantly and harboured ambitions of being a manager himself, despite knowing little about football. He was never on a contract at the club, and was never paid for his six weeks work, nor was he given the chance to invest money in the club as he had first planned.  Gascoigne came close to being appointed manager of Garforth Town in October 2010, and after weeks of talks between his agent and the club he decided to turn down the offer, though reiterated his desire to return to football management.
