Thomas Branagan was an American writer and abolitionist. He is known for his works of literature, particularly Avenia, and for his opposition to slavery. He was described by English professor Christopher N. Philipps as a "kind of American counterpart to John Newton." In 1953, he was described by Lewis Leary in The Pennsylvania Magazine of History and Biography as "one of America's most prolific authors during the first two decades of the nineteenth century."
