SKN St. Pölten were formed after the dissolution of their unofficial predecessor FCN St. Pölten in June 2000. The new club took over all FCN St. Pölten infrastructure, including the stadium and the Bundesliga junior center. Although the normal rules state that new clubs must start in the lowest possible division, due to the acquisition of the Academy system, SKN St. Pölten were allowed to participate in the 2nd League West, the fifth level of Austrian football. In their first season in existence, the team won the 2nd League championship, and were therefore promoted to the fourth tier. In the 2001–02 season, SKN St. Pölten won their second successive title and hence were promoted into the Regional League East. In the same year, they also appeared in the final of the Lower Austria Cup, but were beaten by Theresienfeld. In the 2002–03 season, the team finished twelfth, but improved the following year to finish in fourth. In the 2004–05 season the club attained sixth place in the league and had a run in the ÖFB Cup which included victories over SV Wörgl, SW Bregenz and a sensational 5–1 victory against Austria Salzburg in the third round. In the quarter-finals, St. Pölten, were soundly beaten by Austria Wien 6–0. St. Pölten finally achieved their third promotion in the 2007–08 season, going 24 games unbeaten during one period of the season. They have since remained in the Austrian Football First League, finishing four times in 5th and three times in 4th. During the 2013–14 season the club reached the final of the Austrian Cupfor the first time in their history. In the final, St. Pölten played Red Bull Salzburg but failed to repeat their stunning third round victory from 2002–03, losing 4–2. However, they qualified for the 2014–15 UEFA Europa League as Red Bull Salzburg had already qualified for the 2014–15 UEFA Champions League by virtue of winning the Austrian Football Bundesliga. In the second qualifying round they played Botev Plovdiv of Bulgaria, winning 3–2 on aggregate after losing the first leg 2–1. In the third qualifying round they played PSV Eindhoven, losing 2–4 on aggregate, thus ending their first foray into a continental competition. St. Pölten achieved promotion into the Austrian Bundesliga by winning the First League in 2015–16.
SKN St. Pölten currently has ten youth teams between for children from the age of 7 to 15, with a total of 150 children and youths.
