The Andijan Reservoir, known as the Kempir-Abad Reservoir in Kyrgyzstan (Uzbek: Andijon suv ombori; Kyrgyz: Кемпир-Абад суу сактагычы), is a reservoir formed by the Andijan Dam on the Kara Darya River in the Ferghana Valley. Following the dissolution of the USSR, the reservoir became a source of dispute between Kyrgyzstan and Uzbekistan, with each country claiming ownership. In 2022, the two countries signed a border demarcation deal, according to which Kyrgyzstan reportedly ceded control of the reservoir in exchange for agricultural land elsewhere in Uzbekistan. The agreement sparked protests in Kyrgyzstan, which were clamped down by the Kyrgyz government.
The Andijan reservoir has a maximum surface area of 56 square kilometres (22 sq mi), and an estimated volume of 1.9 cubic kilometres (0.46 cu mi).
