KA was founded on January 8, 1928, in the home of Margrét and Axel Schiöth, at Hafnarstræti 23, with the goal of promoting sports in Akureyri.

The first time the two Akureyri clubs, KA and Þór, combined forces was against recent league champions Valur in the middle of July 1942.

The positive results gave impetus to unification ideas and in 1943 for the fourth time a team from Akureyri played in Úrvalsdeild karla.

But now it sailed under the flag of Íþróttaráð Akureyrar (In english Akureyri Sports Council) and not KA as in all the previous times.

In 1974, the two respective sports clubs ended their collaboration and started sending teams separately as KA and Þór.

Good signings, preseason success, and the experienced coach Bjarni Jóhannsson, who took over in 2013, led many pundits to predict that KA would be promoted to the top flight with ease.

Under new management with Tufegdzic at the helm and notable acquisitions like Hallgrímur Mar Steingrímsson, Guðmann Þórisson, and Ásgeir Sigurgeirsson, the team comfortably won the second division.

[9] Moving into the 2022 season, KA continued its upward trajectory, clinching its second-best result ever in the Besta deild karla.

Nökkvi Þeyr Þórisson showcased an outstanding performance throughout the season, earning recognition as the league's best player and top scorer with 17 goals.

[14] The team also had a relatively successful UEFA Europa Conference League campaign, defeating Connah's Quay Nomads and Dundalk, with their journey coming to an end against Club Brugge.

KA formerly played at Akureyrarvöllur close to downtown Akureyri but have since moved all games to Greifavöllurinn, a temporary arena at the club's training base, KA-Heimilið in the Lundarhverfi neighborhood where a new permanent stadium is also being built.

[17] Since 1999, KA has fielded a joint women's team with neighbouring club Þór Akureyri under the name Þór/KA in the top-level league Úrvalsdeild.
