In Turkic mythology, Chesma İyasi (Turkish: Çeşme İyesi or Bulak İyesi sometimes Pınar İyesi; Azerbaijanese: Bulaq İyesi, Tatar: Çişmä İyäsi) was a cat-shaped spirit who lurked in wells or fountains and tempted youths to their deaths. As a female spirit that resides in water, she can be seen as a type of naiad. Kuyu İyesi is a type of Çeşme İyesi. Unlike the Çeşme İyesi, they are benevolent spirits who protect the wells in which they make their homes.
