Edward Jones Stephen (also Stephens;^[1] December 1822 – 10 May 1885), often known by his bardic name of Tanymarian, was a Welsh musician, singer and composer, mainly of hymns and songs.

He was born in Maentwrog, Merionethshire, into a musical family.^[2] He went to school at Penralltgoch and was then apprenticed to his brother, William. He began preaching and in 1843 he went to the Congregational college at Bala to train as a minister. While there he changed his name to Edward Stephen to avoid confusion with another Edward Jones. In 1847 he became a minister at Dwygyfylchi in Caernarfonshire and in 1852 he composed an oratorio entitled Ystorm Tiberias. In 1856 he moved to another chapel at Llanllechid, and two years later he composed a requiem in memory of John Jones, Talysarn. He composed many hymns and also wrote books and articles about music, in the Welsh language.
