Kotzen is a municipality in the Havelland district, in Brandenburg, Germany.
Since one English translation of the German verb "German: kotzen" is "to vomit", the town was jokingly incorrectly referred to in Ripley's Believe It or Not! under the title "Barfburg". More prosaically the name probably comes from the Slavonic-German noun "Kotzen" which means market place, as per the Theater an der Kotzen, Divadlo v Kotcích in Prague.
Explorer Karl Klaus von der Decken was born in Kotzen in 1833.
