Kirkcaldy YM Junior Football Club was formed in 1970. The YM brought Junior Football back to the town after the demise of Nairn Thistle JFC two years earlier. The club was started to supplement the highly successful Youth Football set up at the YM. The aim of the Junior side throughout the seventies and eighties was to provide the opportunity for younger players to experience football at a higher level. And avoid losing talented young players to other Junior Clubs in Fife. The policy of providing these opportunities to young people led to limited success in the early years, mainly due to the clubs amateur status in the Junior Association.

The YM played for two seasons at Smeaton Park (formerly the home of Nairn Thistle JFC), a stones through away from the current pitch at Denfield Park. Following the building of the new factory by Nairn Williamson. The club was forced to ground share at Coaltown of Wemyss with the now defunct Frances Colliery Junior Football Club. In 1976 the club moved back to Kirkcaldy and played at Windmill Park. The club became established in the east of Kirkcaldy for thirteen seasons. The one difficulty encountered by the club during this period, was the inability to host Scottish Junior Cup ties. Unfortunately, Windmill Park was never enclosed and the club were never allowed to play a Scottish tie on their own ground. The development of Denfield Park in 1990 provided the club with an opportunity to move once again, this time, to a great playing surface and a fully enclosed arena. The park and changing facilities at Denfield are owned by Fife Council with the YM given exclusive use for all games.

Over the years the club has experienced limited success on the park. For some people with an affiliation to the club, this is difficult to understand, given the size of Kirkcaldy and the wealth of talented players from the town. Achievements include winning the Fife Junior Association 2nd Division Championship in season 1979-80. The club also featured in two finals in the 80's losing to Tulliallan Thistle in a local cup, and then similarly losing to St Andrews United in the Fife Cup final in 1988-89. Most recently in season 2004-05 the club featured in the final of the ACA Sports league Cup losing to Hill of Beath Hawthorn.

The Scottish Junior Cup is the premier competition for all Junior Clubs in Scotland. The YM's best shot in this competition came three years ago when the club reached the 5th Round only to loose by a solitary goal to Petershill at Denfield Park. To reach that stage of the competition the club accounted for Ayrshire giants Glenafton, previous winners of the Cup. In what was one of the clubs most famous victories a single goal from striker Liam Baillie silenced the home crowd. You have to go back some 29 years to remember the YM's greatest ever result in the Scottish Cup. In the days when Junior Football attracted large crowds, YM played before their largest ever crowd when they travelled to meet second favourites to win the Cup, and then Glasgow giants Petershill. That day the local Glasgow press were predicting an easy victory for the home side over their opponents from Fife. In a remarkable eight minute period in the second half, YM striker Jimmy Murray scored a hatrick to ensure the YM went home victorious.

Throughout the years the club have fielded some talented players, many of whom have gone on to play Senior Football. Players who have stepped up to the Senior Grade include, David Hunter, Thomas Houston, Billy Martin and John Wright to Raith Rovers, Alex Thomson to East fife, Ian Paterson to Brechin City and Bobby (Dr) Robertson to Dunfermline Athletic.

In the early 70's the YM as an Association produced some of the best players in Scotland, unfortunately their talent was such that they were much to good to play Junior Football. A number of young players stepped up to the Senior Grades directly from Under 18 Football. Kenny McNaught (son of Rovers legend Willie McNaught) signed for Everton, and later went on to win a European Cup winners medal with Aston Villa. Alan Young went to Leicester City. Martin Henderson and Derek Matthew signed for Glasgow Rangers. Later in is career Derek had a short spell back playing with the YM Juniors.

Unfortunately, due to the loss of a full playing squad the YM was forced to take out non playing membership of the Scottish Junior Football Association in season 2007-08. Following a Public meeting in February 2008, a new Committee was formed and the club is now back playing in the East Junior League.
