2023 Icelandic Cup

The 2023 Icelandic Cup, also known as Mjólkurbikarinn for sponsorship reasons, was the 64th edition of the Icelandic national football cup. The winners qualified for the 2024–25 Conference League first qualifying round.

Víkingur Reykjavík won the cup on 16 September 2023 with a 3–1 win over KA, their third consecutive Icelandic Cup win and fifth overall. Since they qualified for the Conference League based on league position, the Conference League spot for winning the cup was passed to the fourth-placed team in the 2023 Besta deild karla.
