The Slovenian Football Cup (Slovene: Pokal Nogometne zveze Slovenije, pronounced [pɔˈkáːl nɔɡɔˈméːtnɛ ˈzʋéːzɛ slɔˈʋèːnijɛ]) is the top knockout tournament of Slovenian football and the second most important football competition in Slovenia after the Slovenian PrvaLiga championship. The cup was established in 1991 following the breakup of Yugoslavia. Since 2020, it has been known as Pokal Pivovarna Union after its headline sponsor, the Union Brewery.

As of 2023, a total of 17 clubs have reached the cup final; the most successful side in the history of the competition is Maribor, who have triumphed 9 times in their 15 cup final appearances. They are followed by Olimpija (1945), Koper, and Olimpija (2005), who won four titles each. Primorje hold the record for most appearances in the final without winning the title, finishing as runners-up in three consecutive finals between 1996 and 1998. Aluminij and Nafta 1903 are the only sides from outside the top flight which managed to reach the cup final, having finished as runners-up in 2002 and 2020, respectively.

Olimpija are the defending champions, having beaten Maribor 2–1 after extra time in the 2023 final.
