Björn Håkan Vikström (born 17 July 1963) is a Finnish prelate who served as Bishop of Borgå between 2009 and 2019.

He was ordained a priest in 1988, after which he has served as a pastor in Hanko and in the Matteus Church of Helsinki, as well as a chaplain for 15 years in the parish of Kimito and Västanfjärd.

Vikström's liberal Bible-mindedness was an old problem, and the discussion particularly concerned his acceptance of homosexual persons.

Nonetheless, he won the 2009 bishop's election in the second round against Sixten Ekstrand in 250-199 votes.

Vikström was nominated for Archbishop of Turku in 2018, but lost to Tapio Luoma.
