Stefán Arnar Gunnarsson (13 March 1978 – c. 2 April 2023) was an Icelandic handball coach and player.
During his career, he coached several teams in Iceland, Norway, Germany and the Faroe Islands.
Later, it turned out that Aðalsteinn did not have the board's support in the matter[3] and Stefán Arnar was reinstated a week later.
[6] In February 2022, he was hired as the interim coach of HK women's team, following the firing of Halldór Harri Kristjánsson.
[9] Following his death, Stefán's brother, handball coach Samúel Ívar Árnason, heavily criticised family members of players for their treatment and undermining of Stefán Arnar to force preferable treatment of certain players and the HK club for his firing shortly before his death.
