Yurii Alekseevich Mitropolskiy (; 3 January 1917 – 14 June 2008) was a renowned Soviet and Ukrainian mathematician known for his contributions to the fields of dynamical systems and nonlinear oscillations. He was born in Poltava Governorate and died in Kyiv. He received his Ph.D. from Kyiv University, under the supervision of theoretical physicist and mathematician Nikolay Bogolyubov. Mitropolskiy is one of the most frequently joint-published mathematicians known, with at least 240 collaborators. Mitropolskiy was a member of Communist Party of USSR since 1945.
