Fussball Club Vaduz is a Liechtenstein football club from Vaduz that plays in the Swiss Super League. The club plays at the national Rheinpark Stadion, which has a capacity of 5,873 when all seated but has additional standing places in the North and South ends of the ground, giving a total stadium capacity of 7,838. They currently play in the Swiss Super League following promotion from the Swiss Challenge League after the 2019–20 season. Vaduz is unique in that it represents its own national association in the UEFA Europa League when winning the domestic cup, whilst playing in another country's league. This is due to Liechtenstein not organising its own league.
Vaduz have historically had many players from Liechtenstein, many of whom have played for the Liechtenstein national team, but nearly all these players have moved abroad, and now the majority of the first team squad are foreign players from different areas of the world. The signing of experienced goalkeeper Peter Jehle from Tours and Franz Burgmeier from Darlington boosted the Liechtensteiner contingent to six by the start of the 2009–10 season.
