Boris Ivanovich Morozov (Борис Иванович Морозов in Russian) (1590 - 1661), Russian statesman and boyar, head of the government in mid 17th century. He was a tutor of Aleksey I.

Morozov supervised a number of government departments (called prikazy; sing., prikaz) – Grand Treasury, Streltsy, Pharmacy, and Payroll. Aspiring to increase treasury’s income, Morozov reduced salaries of state employees and introduced a high indirect salt tax. These measures caused the Moscow revolt of 1648. The rebels demanded the hand over of Morozov, but the tsar hid him in his palace and then sent him in a fictitious exile to a monastery. After four months, however, Morozov returned to Moscow.

In 1649, Morozov took active part in preparing Aleksey’s legal code called Ulozheniya Alexeya Mikhaylovicha and continued secretly to run the government until late 1650s. He owned 55,000 peasants, mills, distilleries, factories that produced iron, bricks, and salt.
