Sarah Mkhonza (born Sarah Thembile Du Pont; 7 May 1957) is a Swazi writer, educator and women's rights activist living in the United States.
Mkhonza received a PhD from Michigan State University. She worked as a journalist for the Times of Swaziland and The Swazi Observer and taught English and Linguistics at the University of Swaziland. Because her writing was critical of the authorities in Swaziland, she was ordered to stop writing. Subsequent threats and assaults led her to seek political asylum in the United States in 2005.
