Robert Mugabe became the first prime minister of Zimbabwe, beginning a 37-year period in power.

Robert Gabriel Mugabe was a Zimbabwean revolutionary and politician who served as the second president of Zimbabwe from 1987 until he was deposed in a coup in 2017. He previously served as the first prime minister and was also the Leader of the Zimbabwe African National Union (ZANU) from 1975 to 1980 and led its successor political party, the ZANU – Patriotic Front (ZANU–PF) as its First Secretary, from 1980 to 2017.

The prime minister of Zimbabwe was a political office in the government of Zimbabwe that existed on two occasions. The first person to hold the position was Robert Mugabe from 1980 to 1987 following independence from the United Kingdom. He took office when Southern Rhodesia became the Republic of Zimbabwe on 18 April 1980. This position was abolished when the constitution was amended in 1987 and Mugabe became president of Zimbabwe, replacing Canaan Banana as the head of state while also remaining the head of government. The office of prime minister was restored in 2009 and held by Morgan Tsvangirai until the position was again abolished by the 2013 Constitution of Zimbabwe.
