Joseph Thomas Wilson (c. 1837 – September 25, 1891) was an American journalist, politician, and author. He served in several regiments, including the 54th Massachusetts Infantry Regiment, during the American Civil War. After the war's end, he was the publisher of several Reconstruction-era publications and a radical member of the Republican Party, active on a state level. Wilson was also a successful author; his 1888 The Black Phalanx sold well and has been described as the "most comprehensive study of African American military service" of the era.
