John Alfred Williams (December 5, 1925 – July 3, 2015) was an African American author, journalist, and academic.

The Man Who Cried I Am, a fictionalized account of the life and death of African-American writer Richard Wright, introduced the King Alfred Plan – a fictional CIA-led scheme supporting an international effort to eliminate people of African descent.

[8] In 2003, Williams performed a spoken-word piece on Transform, an album by rock band Powerman 5000.

Williams married Lori Isaac in 1965 and moved in 1975 from Manhattan to Teaneck, New Jersey, as it was a place that "would not be inhospitable to a mixed marriage".

[13] Williams' personal papers, including correspondence and photographs, are held at Rare Books, Special Collections, and Preservation, River Campus Libraries at the University of Rochester.
