Olof Björn Dreijer (born 27 November 1981) is a Swedish DJ and record producer, best known as a member of the electronica duo The Knife, formed with his sister Karin Dreijer Andersson.

Although The Knife very rarely performed live concerts, Olof performs as DJ Coolof in nightclubs across Europe. He does not perform at nights or festivals without equal gender representation on the lineup of artists - no more than 50% people who identify as men.

In late 2009 and early 2010 Olof released four EPs under the pseudonym Oni Ayhun.

In late 2010 Olof released a remix of Emmanuel Jal's "Kuar". In 2011, Olof produced the song "Jam" by Planningtorock from the album W.
