The club was founded as Chenecks FC in 1946 under the guidance of George Lloyd, well known Coroner Sergeant of the Borough Police. The formation of the club was to enable boys at the rugby-playing Northampton Grammar School to play football. The club's unusual name is derived from the School Houses, Chipseys, Spencer, Beckett and St Crispins.

In 1960 the Old Northamptonians Association invited the club to become one of their sports sections, thus Chenecks became ON Chenecks and relocated to the Billing Road sports ground.

In 1969 Chenecks joined the UCL, winning promotion to Division One in 1973, finishing runners up to Belsize despite losing only one match all season! Success continued higher up, as Chenecks won Division One by 14 points in 1978. They had to settle for second place twelve months later, but regained the title in 1980. A lack of suitable facilities at Billing Road denied Chenecks a place in the Premier and fortunes soon declined. Chenecks beat Tam O'Shanter from Coventry to win the 1985 Daventry Charity Cup final and in 1994 they were Northants Junior Cup runners-up, losing 1-0 to Vanaid.

In the 2009–10 season the club won its first major honour since the Daventry Charity Cup, under the guidance of Andy Marks when they picked up the Junior Cup with a 1 - 0 victory over local rivals Silbey F.C. at Nene Park. The 2010–11 season started with a change at the helm when rookie manager Graham Cottle accepted the vacant manager's position, and he remains very much at the helm of the club today, having steered the club to a further Junior Cup success in 2013/2014,and again in 2014/2015.

The club's youth ranks have produced a number of professional players including Jim Hall (Northampton and Peterborough), Ricky Walker (Coventry and Northampton) and Peter Cooke (Northampton).

Founder member Corbett Cresswell played in FA Amateur Cup finals with Bishop Auckland, while the club's longest serving player is Claude Hasdell who started in 1953 with the minors and played until 1991, with brief spells at Northampton and Wellingborough. Former players also include Premiership referee Pete Walton.

The club fielded their first Girl’s team in 2011/2012.

The 2013/2014 season saw some big changes to the club with the addition of the new FA -funded flood lights and ground improvements which have taken place at Billing Road. The changes were largely due to the hard work and perseverance of the Chairman Eddie Slinn. The changes bring the club in line with FA regulations and marked a turning point in the club’s history.

Success followed on the pitch too in the 13/14 season with the club finishing 6th in the division and lifting the Junior cup at Sixfield’s after beating Brixworth 3-0 in the final. This Success was again repeated at the end of 2014/2015 with the club copying the feat from the previous season by finishing 6th place in the league and retaining the Junior Cup by beating local rivals Northampton spencer at Sixfields 1-0.

The 2015/2016 season saw the club enter the FA Vase for the 1st time.

After further ground improvements including the addition of a seated stand, ON Chenecks 1st Xl were successfully promoted to the UCL Premier division after finishing runners-up in Division 1 at the end of season 2015/2016. The club are set to enter the FA Cup for the first time in 2016/2017. The Reserves finished the season in 4th place.

The U18s won the 2015/2016 NSYL Cup when they defeated Kettering 1-0 in the final at Raunds. A fine performance, capping a good season in this league, where they also managed a credible 4th place. All the boys were effectively under 17 so will be available again next season. As a footnote nearly all of the boys have played for the men’s reserve team this season.
