佩托（古希腊语：ΠειΘω、拉丁语：Peitho）也译为皮托、珀托或珀伊托，是希腊神话中的信仰、劝说、劝导、劝诱女神和结婚女神，是艺术信仰的化身。为赫耳墨斯和阿佛洛狄忒之女，也是阿佛洛狄忒的伴随神（也有的说佩托是阿佛洛狄忒的别名）或小爱神厄洛斯的随从。其在罗马神话中被称为“苏阿得拉（Suadela）”或“苏阿达（Suada）”。

崇拜佩托的主要地区是雅典。希腊化时代的诗人赫耳墨西阿那克斯（Hermesianax） 把佩托也视作美惠三女神之一，和雅典人所崇拜的2位古老丰饶女神奥克索（Αυξω，Auxô / Auxo、“生长”）和赫革摩涅（΄Ηγεμονη，Hêgemonê / Hegemone、“女王”）一起被视作美惠三女神。

Peitho is also the name of an Oceanid. See 118 Peitho for the asteroid.

In Greek mythology, Peitho /piː.θɔː/ (Ancient Greek: Πειθώ Peithō "Persuasion") is the goddess who personifies persuasion and seduction. Her Roman name is Suadela or Suada.

Pausanias reports that after the unification of Athens, Theseus set up a cult of Aphrodite Pandemos and Peitho on the south slope of Acropolis at Athens. According to the same author, they had also a sanctuary and a cult at Sicyon. In her role as an attendant or companion of Aphrodite, Peitho was intimately connected to the goddess of love and beauty. Ancient artists and poets explored this connection in their works. The connection is even deeper in the context of Ancient Greek marriage because a suitor had to negotiate with the father of a young woman for her hand in marriage and offer a bridal price in return for her. The most desirable women drew many prospective suitors, and persuasive skill often determined their success.
