Thomas Lovell Beddoes (June 30, 1803 - January 26, 1849) was an English poet and dramatist. He was son of Dr. Thomas Beddoes, a friend of Coleridge, and Anna, sister of Maria Edgeworth. He was educated at Charterhouse and Pembroke College, Oxford. In 1822 he wrote The Brides' Tragedy, an blank verse drama that was published and well reviewed.

In 1824 he went to Göttingen to study medicine. He was expelled, and then went to Würzburg to complete his training. At this period he became involved with radical politics. He was deported from Bavaria in 1833, and had to leave Zürich, where he had settled, in 1840.

He continued to write, but published nothing. His play Death's Jest-Bookwas published after his death by friends in 1850, and his Collected Poems in 1851.

He led an itinerant life after leaving Switzerland, returning to England only in 1846, before going back to Germany. He became increasingly disturbed, and committed suicide in 1849.
