Airdrieonians F.C. was a Scottish Football team that became defunct at the end of the 2001/02 season.

The team was founded in Airdrie, North Lanarkshire in 1878 as Excelsior Football Club, changing its name to Airdrieonians Football Club in 1881. The club enjoyed its most successful era in the 1920s, finishing in second place in the Scottish League Championship four years in a row in 1923, 1924, 1925 and 1926. Airdrieonians also appeared in four Scottish Cup finals, winning the competition in 1924. In the 1992/1993 season the club competed in the European Cup Winners Cup as a result of being losing finalists in the Scottish Cup to League winners Rangers the previous season.

The club went out of business on 1 May, 2002 after years of overwhelming debts, its last match was played at Ayr United where it was abandoned after "fans" invaded the pitch breaking a goalpost. Despite finishing second in the Scottish First Division that season, it would not have been eligible in any case to receive the financial benefits of playing in the Scottish Premier League the following season.

A new team in Airdrie emerged the following season under the banner of Airdrie United F.C. but their bid for league status was rejected by member clubs as Gretna's application had already been accepted. When all seemed lost chairman Jim Ballantyne bought Clydebank who had financial difficulties of their own and effectively killed them by renaming them 'Airdrie United F.C.' moving them to Airdrie and changing their strip.
