Airdrieonians Football Club are a Scottish professional football team in Airdrie, North Lanarkshire, who are members of the Scottish Professional Football League (SPFL). They were formed in 2002 as Airdrie United Football Club following the liquidation of the original Airdrieonians club, formed in 1878. The club's official name was changed in 2013 with the approval of the Scottish Football Association to the traditional name of Airdrieonians. As with the previous club, this is often colloquially shortened to simply "Airdrie".
The club have won two trophies in their short history – the Scottish Second Division in 2003–04 and the Challenge Cup in 2008–09. Once described as "the luckiest team in the Scottish League", the club have benefited in league division placements due to other club's misfortunes on three occasions (2008, 2009 and 2012).
