Aleksei Mikhailovich Chaly (Russian: Алексей Михайлович Чалый; born 13 June 1961) is a businessman and formerly de facto mayor of Sevastopol. He declared himself mayor in February 2014, amidst the Crimean crisis, after the resignation of Volodymyr Yatsuba, the Viktor Yanukovych-appointed mayor. With Chaly as mayor, Sevastopol participated in the March 2014 referendum in which Crimea voted to separate itself politically from Ukraine and accede to Russia. On 1 April 2014 he was appointed as Governor of Sevastopol City by Russia. On 14 April, he was replaced by Sergey Menyaylo.
