The Fourth Massimov Government (Kazakh: Мәсімов төртінші үкіметі, romanized: Mäsımov törtınşı ükımetı; Russian: Четвёртое правительство Масимова) was the 10th composition under the Government of Kazakhstan, headed by Prime Minister Karim Massimov.

It was formed on 29 April 2015, following the re-election of President Nursultan Nazarbayev in the 2015 presidential election.

After briefly resigning, as per constitution, Massimov under parliamentary approval was reappointed by President Nazarbayev on the same day, to continue his role as prime minister.

Many ministers from the previous cabinet retained their positions, while new appointments were made in key ministries, reflecting the administration's goal of ensuring economic stability amidst ongoing economic stagnation.

His first deputy, Bakhytzhan Sagintayev, succeeded him as the head of the government after being confirmed by Parliament the following day.
