莎孚（古希腊文：Σαπφώ；拉丁化：Sappho），公元前7世纪希腊的女同性恋者。一生写过不少情诗、婚歌、颂神诗、铭辞等。着有诗集九卷，大部分已散轶，现仅存一首完篇、三首几近完篇的诗作，（最新一首刚在2005年出版）以及若干断句，在一首嫁名柏拉图的短歌中，莎孚被称「第十缪斯」。周作人早年曾译介她的诗歌。莎芙是女同性恋者，西方语言中「女同性恋者」一词（例如德语：Lesbe，法语：lesbienne，英语：lesbian），即源自其居住地莱斯博斯岛（现代及古希腊语：Λέσβος，古希腊语拉丁字母转写：Lesbos，现代希腊语拉丁字母转写：Lesvos）。

Sappho (/ˈsæfoʊ/; Attic Greek Σαπφώ [sapːʰɔ̌ː], Aeolic Greek Ψάπφω, Psappho [psápːʰɔː]) was a Greek lyric poet, born on the island of Lesbos. The Alexandrians included her in the list of nine lyric poets. She was born sometime between 630 and 612 BCE, and it is said that she died around 570 BCE, but little is known for certain about her life. The bulk of her poetry, which was well-known and greatly admired through much of antiquity, has been lost, but her immense reputation has endured through surviving fragments.
