Billy Abner Mayaya (born August 24, 1964) is a Malawian human rights activist, artist, poet and theologian.
He began work as a teacher in Malawian private secondary schools teaching English, French and History.
In 2002, together with a colleague Robson Chitengo, he called for the impeachment of the then State President of Malawi, Bakili Muluzi after rumors that he was planning for an unconstitutional third term.
Mayaya publicly apologised for the blunder, whereas Chitengo resigned with intentions to run as a Parliamentary candidate in by-elections.
He was subsequently arrested and charged with sedition together with lawyer Habiba Osman, Ben Chiza Mkandawire, Brian Nyasulu and Comfort Chitseko.
