潘达雷昂 (希腊语：Πανταλέων)为印度-希腊王国国王。

潘达雷昂统治期间约为公元前185年到公元前180年间，关于他的纪录可说是在相当迷离的，可能为是同时期德米特里一世的副王或是德米特里的继承者。亦有为德米特里兄弟的说法。他也是第一个希腊君主铸造印度式的青铜钱币，可能是因他的统治根基在印度的阿拉霍西亚和健驮逻的原故。

从他有限的钱币上来看，统治期间并不长，在已知的钱币证据上，可推测他可能被阿加托克利斯取代。令人注目的是他曾发行白铜合金的钱币，但此技术之前仅中国持有，可视为与中国进行贸易或技术交流的证据。

Pantaleon (Greek: Πανταλέων) was a Greek king who reigned some time between 190–180 BCE in Bactria and India. He was a younger contemporary or successor of the Greco-Bactrian king Demetrius, and is sometimes believed to have been his brother and/or subking. He was the first Greek king to strike Indian coins, peculiar irregular bronzes which suggests he had his base in Arachosia and Gandhara and wanted support from the native population.
