Runcorn Town were formed at the start of the 1967/68 season under the name of Mond Rangers. They played for the first few years in the Runcorn Sunday League, and in 1974/75, made the decision to try Saturday football in the impressive Warrington and District League (WDL).

In their first season they finished as Runners Up in Division Five, and after amalgamating with Premier Division side ICI Weston for the following season, became one of the strongest sides in the league. They remained in the WDL until 1984 when they were elected to join the West Cheshire League (WCL) Division Two. A reserve team was also set up playing in the WDL and a youth team established.

Mond established themselves as a good, solid mid-table team until the 1991/92 season when they won their first silverware in the West Cheshire Bowl as well as a respectable sixth place finish. The following season they finished third in the league and reached the Bowl final, and improved again the following season by finishing third in the league, scoring 100 goals, and regaining the Bowl.

Promotion finally came in 1994/95 when they finished second in the league scoring 118 goals. They also reached the Final of the Cheshire Amateur Cup but lost 2-1 to Poulton Victoria in a match played at Prenton Park, Tranmere.

This period of success was mirrored throughout the club. The youth team won the league in 1993/94, and were runners up in the Cheshire Youth Cup. The following season they went one better in the Cheshire Youth Cup and also won the Warrington Youth Cup.

The reserves meanwhile switched to the Chester League, winning Division Two in 1996/97 and then Division One the season after. They did not lose a game for two seasons. The reserves were then successful in joining the WCL's newly formed Division Three in 1998.

1998 also saw a women's team play at Mond for the first time, with the team playing in the North West Ladies League. They won Division Three at the first attempt and also the League Cup. The following year they finished as runners up in Division Two, and with it promotion to Division One. In 2001/02, they achieved their finest hour with an away tie in the cup at Manchester United Ladies, where they went down 4-3. The ladies team left Mond in 2001 to merge with Liverpool FC Ladies.

Meanwhile the first team struggled in WCL Division One, despite sharing the Bill Weight Memorial Trophy in that first season. They were relegated for the first time in the clubs history in 2001/02.

The 2004/05 saw success return to the club with the first team finishing as runners up in Division Two, winning the Runcorn Senior Cup and reaching the final of the Bowl. The reserves won WCL3, the WCL Shield, and also reached the final of the Warrington Guardian Cup. Both teams were promoted.

Ahead of the 2005/06 season, the club changed their name to Runcorn Town in order to try and bring a more professional look to the club in general, and hopefully increase support from both businesses and individuals in the local community. A decision was also made to try and improve facilities at the club with a view to joining the North West Counties League.

Although progressing off the pitch, the team had mixed fortunes on it. The youth team finished third in the league and won the league cup. The reserves adapted well to WCL2 and the first team got off to a good start by winning the Bill Weight Memorial Cup.

The Runcorn Cup was added but on the final day of the season, Town slipped into the relegation places for the first time to suffer a heartbreaking relegation. To make matters worse, although the reserves finished 6th in WCL2, they were also relegated as clubs cannot have more than one team in each division.

Town quickly regrouped and bounced back by winning the WCL2 for the first time in the clubs' history. The reserves also had a new look team with the club disbanding the youth team and "merging" it with the reserves, and despite most of the team playing open aged football for the first time, finished in sixth place in the league.

The 2007/08 season was probably the most successful in the clubs' history, with the team opening the season by sharing the Bill Weight Cup with West Kirby after a thrilling 3-3 draw in the Final. The club also won the Runcorn Cup, were runners up in the Pyke Cup, and finished third in the league, the clubs' highest ever finish. The reserves were disappointed to finish third in the league, but won the West Cheshire Shield.

The following two seasons saw Town continue to push for honours with both the first team and reserves registering top four finishes. Off the field, the transformation of the ground continued with floodlights installed for the first time.

The summer of 2010 saw the club again take a massive step forward. The first team were elected to join the North West Counties Football League (NWCFL) and entered the FA Vase and Cheshire Senior Cup for the first time. In their first season the club achieved promotion to the NWFCL Premier Division as well as reaching the Last 32 of the FA Vase.

The reserves were also in new territory having joined the Cheshire League, whilst the club also reintroduced the youth team who played in the West Cheshire Youth League. The first steps into junior football were also undertaken with an Under 12's team joining the Halton & District Junior League. This has further been expanded upon with the introduction of an Under 9's for the 2011/12 season.
