Starting life as the Sauchie Juveniles, the club enjoyed a lot of success in the 1950s, winning the Scottish Cup four times (1951–52, 1956–57, 1957–58 and 1959–60). Having won every trophy possible as first class Juveniles, in 1961 the Club Secretary, Jimmy Millar, decided to take the Club into the Junior grade, and formed Sauchie Juniors.
In 1962, the Club's second season as a Junior team, it won the East Region League Title using mostly the Juvenile players. The 1970’s saw the Sauchie Juniors win the East Region St Michael's Cup twice, in 1972 and 1974. After winning the East Dryburgh Cup in 1982–83, the team then went on to win the National Dryburgh Trophy against other Dryburgh winners.
The next cup wins came in the 2000’s, lifting the Fife and Lothians Cup in consecutive years in 2002-03 and 2003-04, defeating Glenrothes and Linlithgow Rose respectively.
Prior to the 2006-07 season, the Scottish Junior Football Association (SJFA) restructured. Sauchie found itself in the 15-team East Region, South Division where it finished second in its first season in the division.
Current Manager, Fraser Duncan, took over the team for the 2009-10 season and saw the team to a fourth-place finish in the league. A series of new signings for the next season saw a blend of players arrive at Beechwood Park.
In 2011, the club won the East Region South Division and gained a promotion to the Premier League, winning its first season (2012-13). After a best Super League finish of 5th in 2014-15, the club was relegated the following season but immediately gained promotion with a second Premier League title in 2016-17.
Sauchie Juniors started playing at Fairfield Park, Sauchie, but built a new ground, Beechwood Park, where the club currently plays. Beechwood Park was developed in 2003 with the building of a new stand, enclosure and erection of floodlights.
