Sportklub Union Amstetten, commonly known as SKU Ertl Glas Amstetten for sponsorship reasons is a professional association football club based in the town of Amstetten, Lower Austria, that competes in the Austrian Regionalliga, the third tier of the Austrian football. Founded in 1997, it is affiliated to the Lower Austrian Football Association. The team plays its home matches at Union-Platz, where it has been based since its foundation.
The club was formed in 1997 from a merger of two local clubs; former second division club ASK Amstetten, founded in 1932, and SC Union Amstetten, founded in 1946. Existing rivalries were pushed aside as a new board was founded by members of both clubs headed by chairman Rodolf Brunner.[2] In the 2007–08 season, the club was promoted to the third highest league, the Austrian Regionalliga before being directly relegated to the 1. Niederösterreichische Landesliga again. In 2011, the club returned to the Regionalliga, where they established themselves until the 2017–18 season, where they managed to win promotion to the Austrian Football Second League for the first time.[3] They returned to the third tier Regionalliga in 2024, after suffering relegation as bottom of the table in the 2023–24 season.[4]
After their first successful performance in the Austrian Cup in the 2013–14 season as a Regionalliga side – a victory over the second division club SV Mattersburg and reaching the quarter-finals –[5] they managed to knock out Austria Lustenau in the 2016–17 Austrian Cup, a club playing at the professional level. After a 2–2 draw in regular time, they won the penalty shoot-out.[6] Before that, in the 2015–16 Austrian Cup season, Amstetten had narrowly lost to Rapid Wien on penalties in the second round.[7]
