The KNVB Beker, also known as the TOTO KNVB Beker for sponsorship reasons, is the premier knockout football cup competition in the Netherlands. Established in 1898, it is one of the oldest football tournaments in the country and is organized by the Royal Dutch Football Association (KNVB). The competition involves teams from various levels of Dutch football, including Eredivisie, Eerste Divisie, and amateur clubs. The tournament is known for its unpredictability and the potential for "giant-killing" moments, where smaller teams can upset top-tier clubs. Matches are played in a single-elimination format, culminating in a final held at the De Kuip stadium in Rotterdam, a venue that adds to the grandeur of the event​.

Winning the KNVB Beker is highly prestigious, offering the victor not only a domestic trophy but also a place in the UEFA Europa League. Clubs like Ajax, PSV Eindhoven, and Feyenoord have historically dominated the competition, with Ajax holding the record for the most titles. The tournament also serves as an important platform for clubs to gain European qualification and for players to showcase their talents on a significant stage. The KNVB Beker remains a beloved competition in Dutch football, celebrated for its rich history, competitive spirit, and the excitement it brings to fans across the country.
