23rd Renfrewshire Rifle Volunteers (RV) was a 19th-century football club based in New Cathcart, in Glasgow, which participated in the early seasons of the Scottish Cup.
Its first reported match was against the Eastern second XI.[3] The 23rd R.R.V. met the Eastern's first XI in its first Scottish Cup entry five months later, losing 3–0.
The club reached the second round of the Cup three times. The first time, in 1875–76, was due to the rule at the time that teams advanced after two draws, and the Volunteers held Sandyford twice.[4] In the next two seasons, the club won its first round fixtures, beating Thornliebank in 1876–77 (2–0 in a replay at Cowglen,[5] after a 1–1 draw at home[6]) and Levern in 1877–78.
However, on every occasion, the club lost its third round tie, every time by 1–0; in 1876–77, the club protested the single goal scored by Busby, to no avail.[7] The club's Cup matches were almost all low-scoring affairs, only 12 goals being scored in 10 games.
