Donald Fraser (1 June 1870 – 20 August 1933) was a Free Church of Scotland missionary in Africa and author of six non-fiction books about his almost three decades of work there.

Fraser introduced many innovative practices and policies that were respectful of and responsive to the customs and traditions of the Ngoni people, including: week-long conventions that attracted thousands of Ngoni men, women and children; championing the creation of vernacular village schools; and encouraging indigenous church music and local leadership in the church, including Ngoni women elders.

Fraser's missionary work was the subject of extensive research and analysis by the late T. Jack Thompson, an Irish mission historian and scholar of African Christianity.

In 1922, Fraser received an honorary Doctor of Divinity degree from the University of Glasgow,[15] and he was elected Moderator of the 1922–23 General Assembly of the United Free Church of Scotland.

His wife Dr. Fraser returned his ashes to Malawi for burial at Loudon Mission Station.
