Thomas Wright (9 November 1809 – 17 November 1884) was a Scottish surgeon and palaeontologist.
Wright published a number of papers on the fossils which he had collected in the Cotswolds, including Lias Ammonites of the British Isles.
Wright was born in Paisley and studied at the Royal college of Surgeons in Dublin. In 1846 he moved to Cheltenham, where he became medical officer of health to the urban district, and surgeon at Cheltenham General Hospital. He won the Wollaston Medal in 1878 and became a fellow of the Royal Society in 1879.
After his death part of his fossil collection was sold to the British Museum.
