Joseph Harris (1773 — August 10, 1825) was a Welsh Baptist minister, author, and journal editor. A Welsh language poet, he took the Biblical name of Gomer as his bardic name. On 1 January 1814 he launched the first Welsh-language weekly Seren Gomer ("Star of Gomer") in Swansea.
Gomer was born on a farm in Wolf's Castle, Pembrokeshire. He became a preacher during the religious revival of 1795. He married Martha Symons, and took on Back Street chapel. One of his best-known works, Cofiant Ieuan Ddu, was a biography of his son, John Ryland Harris, who worked as a typesetter for his father's printing press and died at the age of twenty.
