Robert Williams was a Welsh poet who wrote most of his poems about agriculture and nature.

[1] He learned bardic conventions from the well-known teacher Rolant Huw (1714-1802),[2] and himself taught the better known Ioan Tegid (John Jones, 1792-1852) and others.

('Friend of the Cymmrodorion'), Williams wrote an elegy on the death of Richard Morris of Anglesey, and a cywydd on the subject of the Day of Judgement, which Rolant Huw considered in the same class as the work of Goronwy Owen and William Wynn of Llangynhafal on the same subject.

He also wrote a poem to Dafydd Ionawr (David Richards), and exchanged englynion with Twm o'r Nant (Thomas Edwards).

Williams' elegy to the Methodist leader Peter Williams was one of only two works of his to be published, but selections from his work were printed by O. M. Edwards (Cymru Fydd, iv, 41-4; Cymru, ii, 210-3; Beirdd y Bala, 40-8), from whom most of the knowledge about his life comes.
