William Michael "Mike" Campbell (12 October 1932 – 8 April 2011) was a white African farmer from the district of Chegutu in Zimbabwe (formerly Rhodesia).
Together with his son-in-law Ben Freeth, he rose to international prominence for suing the regime of Robert Mugabe of violating rule of law and human rights in Zimbabwe, in the case of Mike Campbell (Pvt) Ltd and Others v Republic of Zimbabwe.
His struggle was the subject of an award-winning documentary, Mugabe and the White African.
