欧忒耳佩（古希腊语：Εὐτέρπη）希腊神话中司抒情诗的缪斯。她的名字来自希腊语词根Εὐ（“好”）和τέρπ-εω（“使高兴”），合起来就是“令人快乐”的意思。

在希腊神话中，欧忒耳佩是宙斯与记忆女神谟涅摩叙涅的女儿。她的形象是个手持长笛或双管长笛的少女。欧忒耳佩喜爱音乐，一些神话指出她是双管长笛（或所有吹奏乐器）的发明者（大多数神话则认为是马耳叙阿斯发明了这种乐器）。

欧忒耳佩曾与河神斯特律蒙结合，并生下了儿子、色雷斯国王瑞索斯，此人在特洛伊战争中被狄俄墨得斯杀死。

小行星27号司箫星的名字来自欧忒耳佩。

In Greek mythology, Euterpe (/juːˈtɜːrpiː/; Greek:Eὐτέρπη, Greek pronunciation: [efˈterpi], Ancient Greek: [eu̯térpɛː]; "rejoicing well" or "delight" from Ancient Greek εὖ 'well' + τέρπειν terpein 'to please') was one of the Muses, the daughters of Mnemosyne, fathered by Zeus. Called the "Giver of delight", when later poets assigned roles to each of the Muses, she was the muse of music. In late Classical times she was named muse of lyric poetry and depicted holding a flute. A few say she invented the aulos or double-flute, though most mythographers credit Marsyas with its invention.
