Hyakunin Isshu (百人一首) is a classical Japanese anthology of one hundred Japanese waka by one hundred poets. Hyakunin Isshu can be translated to "one hundred people, one poem [each]"; it can also refer to the card game of uta-garuta, which uses a deck composed of cards based on the Hyakunin Isshu.

The most famous and standard version was compiled by Fujiwara no Teika (1162–1241) while he lived in the Ogura district of Kyoto. It is therefore also known as Ogura Hyakunin Isshu (小倉百人一首).

One of Teika's diaries, the Meigetsuki, says that his son Tameie asked him to arrange one hundred poems for Tameie's father-in-law, Utsunomiya Yoritsuna, who was furnishing a residence near Mount Ogura; hence the full name of Ogura Hyakunin Isshu. In order to decorate screens of the residence, Fujiwara no Teika produced the calligraphy poem sheets.
