Zhetysu (, pronounced meaning "seven rivers"; also transcribed Zhetisu, Jetisuw, Jetysu, Jeti-su, Jity-su, Жетысу, Джетысу etc. and Yedi-su in Turkish) is a historical name of a part of Central Asia, corresponding to the South-Eastern part of modern Kazakhstan. It owes its name, meaning "seven rivers" (literally "seven waters") in Kazakh, to the rivers which flow from the south-east into Lake Balkhash.
