Koca Musa Pasha (usually referred to as just Musa Pasha; died 22 January 1647, near Euboea) was an Ottoman statesman. He served most prominently as Kapudan Pasha (1645–1647),Ottoman governor of Egypt (1630–1631), Ottoman governor of Budin Eyalet (c. 1636–1638, c. 1640–1644), and Ottoman governor of Silistra Eyalet (1644–1645). He was also a vizier.
Musa Pasha was born into a Bosniak family and attended the Enderun palace school.
Musa Pasha's term as the governor of Egypt was described as brutal and terror-inducing by multiple sources. On the first day of holding divan (government), he had a man's head struck off and his property confiscated, following this with the crucifixion of the son of a local sharif chief. After handing out the various government offices to his friends and servants and facing the displeasure of the sanjak-beys, Mustafa Pasha returned the offices to their previous owners and blamed the incident on an agha, confiscating his residence as ostensible punishment. During his governorship, Musa Pasha took on projects and plans to reform the salary system to his benefit and find methods to claim wealthy locals' inheritances.
In March 1631, sultan Murad IV ordered Musa Pasha to send him troops for the expedition against Persia. Musa Pasha gave command of these troops to emir Kitas Bey, who was of Circassian origins, and imposed a tax on the land in order to pay fort the camels to transport the troops to Persia. Musa Pasha then told Kitas Bey that funds were insufficient for the expedition and that it was canceled. When Kitas Bey protested, Musa Pasha had him killed; on Wednesday, July 9, 1631, the Day of Arafa and the day before Eid al-Adha, a day when the emirs traditionally visited the governor's house to wish him well, Kitas Bey was in attendance despite having second thoughts because of his knowledge of his now-poor standing with the Pasha. Suddenly, Musa Pasha had a group of men spring upon Kitas Bey, one man decapitating him with a single swing of an axe, while up to 40 others stabbed his body as the other emirs stood by in horror.
