Thomas Morgan (also known by his bardic name, Afanwyson) was a Welsh writer, historian and Baptist minister.
Born in Cwmafan on 9 March 1850, Morgan was the nephew of the deacon and bard David Michael (Dewi Afan) whose own poetry was characterised as "Biblical and ethical" in its nature.
Morgan would remain at Caersalem for the next seventeen years, during which time he would become the co-editor of Y Bedyddiwr Bach in 1882 and Yr Heuwr in 1890, as well as publishing the first edition of one of his most notable works, The Place-Names of Wales in 1887.
At Cardiff, he worked with Thomas Powel in reorganising the Salusbury library in the University College of South Wales and Monmouthshire.
