The 35-year-old made 14 appearances for the Gunners last season after re-joining ArsÃƒÂ¨ne Wenger’s side in January, but was unable to reach an agreement over a new deal with the north London club.
“At this stage of my career I couldn’t have wished for a better move,” Campbell told the club’s official website. ”To join a club such as Newcastle United, with its proud tradition, heritage and magnificent support, is absolutely tremendous for me.
“I’d like to thank Chris Hughton for putting his faith in me and aim to repay him and the supporters by giving everything I possibly can to help re-establish this great club in the top tier of English football.
“I just want to play and can’t wait to get started. There’s a real buzz about the place and that’s great. I’ve played at St. James’ Park numerous times and always found it a fantastic place to play, there’s always a tremendous atmosphere.”
Newcastle manager Chris Hughton said: “I have known Sol since he was a lad at Tottenham and am fully aware of what he has to offer. That is experience, quality, calm assurance and leadership. He’s a dedicated professional, a terrific addition to the squad, and I look forward to working with him again.”
Campbell will wear the No5 shirt at St James’ Park next season.
