Oliver Hans Kahn (born 15 June 1969 in Karlsruhe) is a German football goalkeeper. He played for the German national team (from 1995 to 2006) and plays for Bayern München (since 1994).

Kahn is a player obsessed by perfection, is known to train fanatically, but also has the tendancy to erupt in a berserker rage when things go wrong. Because of his seemingly overambitious attitude in the field he is made fun of sometimes in Germany by some comedians and caricaturists, portraying him as a maniac. In 1996, popular German comedian Harald Schmidt lip-synched Kahn, when he angrily shouted at colleague Andreas Herzog, by using ape noises and calling him (Kahn) "gorilla". This achieved cult fame, and from that moment on, fans of the opposing team would taunt him by making ape noises and throwing bananas at him. But since his stellar performance at the 2002 FIFA World Cup, this has mostly ceased.

Recently, Kahn capitalized on his "mad maniac" image in commercials in which he terrified opposing penalty kickers, bested a stadium lusting for his blood and let out loud animal roars. After Kahn lost the No. 1 goalkeeper spot in the German national team to Jens Lehmann, he even sent himself up in ads. In a commercial for the Paulaner brewery, he sits on a bench with a beer and sighs "on the bench, life is best", and in ads for Burger King, he sits on a bench with the caption Olli Kahn proves his size (in German, "size" also means "composure"), a reference to a new, bigger burger.
