The Glasgow Tigers, originally known as the Strathclyde Sheriffs, trace their origins back to 1985 when 50 prospective players put £50 each into a kitty to form the club. The Sheriffs were run by officers from the Strathclyde Police Force and entered their first regular season in 1986 where they managed an 8–2 season, just missing out on the playoffs.
In 1988 the Sheriffs went undefeated and won the Caledonian Bowl with a 46–12 victory against the Ness Monsters.
Reached the semi-finals of the BNGL Premier Division in 1991 and were then disqualified after a player registration scandal. They then missed the following two seasons, before starting again in 1993.
In 1994 they entered the Scottish Gridiron Association and for four consecutive seasons between 1995 and 1998 played all other teams across Scotland.
In 2002 the team rebranded as the Glasgow Tigers. To this day, original Sheriffs players play an integral role in coaching and management of the team and the team maintains a strong link with the local police force.
The team has made seven playoff appearances in total – three as the Sheriffs (1988, 1990, 1996) and four as the Tigers (2002, 2004, 2009, 2016). The Tigers won their division in 2009 and were one game away from making an appearance in a bowl game.
Following the conclusion of the 2016 season, the Tigers were promoted to the BAFA NFC 1 North for the first time.
