Formed in 1968 Ballynahinch United started out in the Newcastle & District Amateur Football League and after winning a number of league titles and the Harry Clark Cup moved to the Amateur League were they have remained for over 30 years.
Progression through Amateur League Division’s to 2A was rapid which coincided with a number of Junior Cup and Cochrane Corry Cup Final appearances which were unsuccessful.
Having used Bell’s Bridge, Dromara and Langley Road, Ballynahinch as their home bases for a number of years the club acquired Millbridge and moved into the Amateur League’s Intermediate 1b section were the club has played for most of the time, except for a period in the mid 1990’s when it gained promotion to Division 1a and reached the final of the Clarence Cup.
By far the club’s greatest achievement was winning the Amateur League’s Border Regiment Cup in 1982 when from Division 1b they defeated British Telecom on penalties.
The club continues to develop and improve its facilities at Millbridge.
