Botkul ({{langx|kk|Боткөл}}; {{langx|ru|Боткуль}}) is a bittern salt lake in the Kazakhstan–Russia border.{{cite web|url=https://maps.vlasenko.net/smtm1000/m-38.jpg|title=M-38 Topographic Chart (in Russian)|access-date=31 July 2022}}

There is no salt mining at the lake. Its waters have a bitter, stinging taste and a strong smell of hydrogen sulfide. The authorities are exploring the potential of developing Botkul as a tourist attraction.[https://water-rf.ru/%D0%92%D0%BE%D0%B4%D0%BD%D1%8B%D0%B5_%D0%BE%D0%B1%D1%8A%D0%B5%D0%BA%D1%82%D1%8B/1949/%D0%91%D0%BE%D1%82%D0%BA%D1%83%D0%BB%D1%8C Water of Russia - Боткуль]
