Original Adidas Newcastle United 2009/10 football shirt

The 2009–10 season was the first time Newcastle United Football Club had played in the Championship following relegation after 16 consecutive years in the Premier League. In the 2009–10 season, they won promotion back to the top division after finishing in first place in the 2009–10 Championship.

Following the club's relegation, the team's pre-season had been dominated by uncertainty over manager, owner and the players. By the time the season began, caretaker manager Chris Hughton was put in charge, and his position was made permanent in October. Despite a blip in October, the club spent almost all of its season in the top three in the division and some blistering home results saw Newcastle automatically promoted by Easter. They confirmed their promotion as winners of the entire division two weeks later, with the club registering 102 points.
