The team play their home fixtures at the Sixfields Stadium since moving from the County Ground in October 1994. Their current sponsor is local Estate agents, Jackson Grundy. They usually play in claret and white, and their main local rivals are Peterborough United, a rivalry which has endured since the 1960s.
Northampton Town joined the Northants League and spent two seasons there before moving on to the Midland League. Only two seasons later they joined the Southern League in the 1901-02 season. In the 1908-09 season manager Herbert Chapman helped the Cobblers to be crowned champions of the Southern League, and they later faced Newcastle United in the Charity Shield at Stamford Bridge where they lost 2-0 . Herbert Chapman left to manage Leeds City in 1912, and went on to win the league championship four times: twice at Huddersfield Town, and twice at Arsenal.
From the 1930s to the 1950s Northampton Town had attempted to rise from the regional Third Division South, but rose only twice and were immediately relegated. The creation of the Fourth Division spurred a brief substantial rise that culminated in the only season (1965-66) of their existence in the top division of English football. In 1970, they lost 8-2 to Manchester United in the FA Cup fifth round. Six of the goals conceded were scored by George Best, who received the match ball (signed by Northampton players) as a reward for his performance.
A financial crisis at the club lead to the foundation of Britain's first Supporters' Trust.
The club finished bottom of the Football League's new Division Three in 1993-94, only avoiding relegation to the Conference because Kidderminster Harriers did not have a satisfactory stadium to join the Football League. Manager John Barnwell was sacked soon afterwards to make way for Ian Atkins, and the club began to move forward. In 1996-97 they won promotion to Division Two, thanks to a playoff final victory at Wembley over Swansea City, and almost made it two successive promotions the following season - but were beaten 1-0 by Grimsby Town in the Division Two playoff final. The club went down a year later and Atkins resigned, but promotion was earned at the first attempt under new manager Kevin Wilson.
Calderwood led Northampton to the play-offs in his first season, where they were knocked out in the semi-finals by Mansfield Town after a penalty shoot-out. In the 2004-05 season, Northampton finished 7th, again in the play-offs, where they were defeated by Southend United. Following this, the manager made substantial changes to the squad, and they enjoyed a successful 2005-06 league season. On April 29, the Cobblers clinched promotion to Football League One for 2006-07, with a 1-0 win at home to Chester City. On May 30 2006, Northampton announced that Calderwood was leaving to join Nottingham Forest as their new manager, and was replaced by John Gorman on June 5.
On December 20, Gorman resigned due to "personal issues" with the side 18th in the table, with Ian Sampson and Jim Barron briefly taking care of first team affairs. He was replaced by former Southampton boss Stuart Gray on January 2 2007.
Gray is enjoying a successful spell at Northampton, making encouraging signings in his first few weeks. The club looks to be going from strength to strength, finishing 14th at the end of the 2006/07 season, 12 points clear from the relegation zone. Gray made radical changes selling Bradley Johnson and allowing Andy Kirk to leave on a free transfer to Yeovil. It appears the clubs finances are also going from strength to strength, with the club and the local council now firm allies things are looking bright for the club and the area with the new Sixfields drawing ever closer.
2007-08 brought Northampton's highest finish in a decade, as they finished ninth with 66 points.
