The 2001–02 season is the sixth in the history of the Glasgow Warriors as a professional side. During this season the young professional side competed as Glasgow Rugby; reverting to their original professional title and dropping the Caledonian name inherited from the Caledonia Reds merger. However, the team gains the epithet Warriors at least from this season. The 2001–02 season saw Glasgow Rugby compete in the competitions: the Welsh-Scottish League, the Celtic League and the European Champions Cup, the Heineken Cup.
