The club played in its first Junior Cup Final at Hampden Park in 1954–55 against Duntocher Hibs before a crowd of 64,976. The game ended 1–1 and Kilsyth won the replay 4–1 before a crowd of 30,000, all four goals being scored by the club's most prolific ever striker Alex Querrie. This feat is still a record to this day. Kilsyth lost the 1957 final against Banks O'Dee (1–0) after being hot favourites. The last final success was in 1967 when they beat Rutherglen Glencairn 3–1 after a 1–1 draw in the first game at Hampden which was played in front of 22,000 fans.
