In 1927, members of
Dunstable Grammar School formed a rugby section, based at Fensomes Field in
Leagrave,
Luton. Unfortunately, the number of regular players dwindled, forcing the closure of the club after only three seasons. In 1948, another group of former pupils made a new start, securing a ground at French's Avenue in
Dunstable and later moving to Skimpot Lane in Luton. In 1954 ground in Bullpond Lane, Dunstable was leased. The event was marked with a match against an East Midlands Invitation XV. It was eventually decided that a new ground was needed and the site at Bidwell Hill in Houghton Regis should be purchased, with the bulk of the financing raised through the sale of the Bullpond Lane site for housing development. In September 1985, the club opened the current clubhouse by hosting an International XV that included six past England Captains. The club has seen several promotions in the past. Highlights include the near perfect 1999/2000 season which delivered victory in all RFU competitions entered, along with League, County and East Midlands Cup success. This culminated in Dunstablians becoming National Intermediate Cup Champions at
Twickenham. A successful period followed; Dunstablians retained the County Cup in 2000/01 and added the Colts Cup to the collection. They lifted the County Cup again in 2005. During 2006/07 Dunstablians also secured the Bedfordshire County Cup, defeating
Bedford Athletic in the process. They then returned to Twickenham for their second Intermediate Cup Final losing 36–46 to
Cornish side
Mounts Bay and finished 3rd in Midlands League 1 (RFU Level 5), their highest ever league placing. After a five-year wait, Dunstablians won the Beds County Cup again by defeating Stockwood Park in 2012, but since then have finished runners up in no less than three successive County Cup Finals. ==Honours==
