普里阿普斯（古希腊语：Πρίαπος，英语：Priapus）是希腊神话中的生殖之神，他是酒神狄俄尼索斯和阿佛洛狄忒之子，是家畜、园艺、果树、蜜蜂的保护神。他以拥有一个巨大、永久勃起的菲勒斯而闻名。在西方，他的名字是“阴茎异常勃起（Priapism）”一词的词源。

由于在帕里斯的评判中，阿佛洛狄忒要比赫拉美丽，因此恼怒的赫拉在阿佛洛狄忒怀孕时，普里阿普斯就在母亲腹中遭到了诅咒。赫拉诅咒他长出硕大而丑陋的各种器官，其中就包括巨大无比且一直挺立的生殖器。普里阿普斯出生后，阿佛洛狄忒发现自己的儿子竟然如此丑陋，于是就将他交给牧羊人抚养。

In Greek mythology, Priapus (/praɪˈeɪpəs/; Greek: Πρίαπος, Priapos) was a minor rustic fertility god, protector of livestock, fruit plants, gardens and male genitalia. Priapus is marked by his oversized, permanent erection, which gave rise to the medical term priapism. He became a popular figure in Roman erotic art and Latin literature, and is the subject of the often humorously obscene collection of verse called the Priapeia.
