Arnór Guðjohnsen (born 30 April 1961) is a former Icelandic footballer who played for R.S.C. Anderlecht, among others, and finished top scorer with that club in the Belgian First Division 1986-87 season. He is the father of FC Barcelona striker Eiður Guðjohnsen.
At 25 he had been asked his biggest wish, to which he replied "to play international football alongside Eiður". However, shortly before a match in Reykjavik in which father and son were finally scheduled to appear alongside one another, young Eiður broke his ankle in an Under-18 tournament. He duly missed the next two seasons, in which time Arnór hung up his boots and bought a fishing rod.
"It remains my biggest regret that we didn't get to play together, and I know it's Eiður's too" said Guðjohnsen.
Guðjohnsen played 73 games for the Icelandic national team and scored 14 goals, four of them in a game against Turkey. He played his last international in October 1997 against Liechtenstein.
