Anna Minerva Henderson (August 8, 1887 – 1987[1]) was a teacher, civil servant, and poet from Saint John, New Brunswick.

She earned her teacher's certificate, but was barred from teaching in Halifax or Saint John on account of her race.

In 1938 she worked for the Department of Mines and Resources' immigration branch, employed as principal clerk.

[1] Henderson worked as a stenographer for the Saint John law firm Fairweather & Stevenson in 1945.

[4] In 2021, as part of their Being Black in Canada feature the CBC produced an article focused on Hendersen titled "Restoring the legacy of a 'trailblazing' Black Saint John writer" that focused on Hendersen's life as an educator, civil servant and author, and on the research currently underway to further explore and promote her legacy as an African-Canadian author.
