The VAK410 (Dutch, "Section 410") was a Dutch Ultras group associated with AFC Ajax. The name comes from the name of their initial stand in Ajax's home stadium, the Amsterdam Arena.
VAK410 was founded on 26 January 2001 by fanatic supporters of the club who were tired of being on the waiting list for the already existing hooligan firm F-side. On that day, young Ajacied Karel organized the first meeting of the group's in the Amstel Cup home match against SBV Vitesse in row 114. The match resulted in a 1–2 loss. However, the club took a positive stance towards the initiative to create more of an atmosphere in the North side of the stadium, and so VAK410 was born. Originally known as the Ajax Ultras, with ajaxultras.nl being the official website, the group relocated to row 415 on 11 February 2001 ahead of the home match against Willem II, right next to the "Away row" for visiting supporters. Ajax' fanzine De Ajax Ster, otherwise known as DAS, reported on the development of the row, despite the low turnout of the ultras during the match. However, two weeks later, on 25 February 2001, the group celebrated its first big success when a large gathering managed to silence the visiting crowd during the home match against FC Utrecht.
The first match in their current location in the stadium, from which they took the name VAK410, was held on 19 August 2001, at which point the group had approximately 400 members. Considered one of the most famous Tifosi groups in the sport, the group considered itself to be an ultra fan group, and it distanced itself from hooliganism. The group dissolved in the summer of 2016, after disagreements with Ajax Amsterdam's management, over the decision of the club's board to move them away from their years long location at VAK 410 of the Amsterdam Arena.
