佩特任山（捷克语：Petřín；德语：Laurenziberg）是捷克首都布拉格市中心的一座山丘，海拔327米，高于伏尔塔瓦河左岸130米。这座山几乎被完全辟为公园，供布拉格居民休闲。这座山出现在弗朗茨·卡夫卡的早期短篇小说《一次战斗的纪录》（Beschreibung eines Kampfes）、米兰·昆德拉的《生命中不能承受之轻》和茨维塔耶娃的《山之歌》（Поэма Горы）中。

从布拉格小城区可以通过佩特任缆车到达山顶，这是一条1891年通车的缆索铁路。

Petřín (327 m) is a hill in the center of Prague, Czech Republic. It rises some 130 m above the left bank of the Vltava River. The hill, almost entirely covered with parks, is a favorite recreational area for the inhabitants of Prague. The hill (in German known as Laurenziberg) is featured prominently in Franz Kafka's early short story "Description of a Struggle" and briefly in Milan Kundera's novel The Unbearable Lightness of Being.
