Thomas Henry Wyatt (9 May 1807 – 5 August 1880) was an Anglo-Irish architect. He had a prolific and distinguished career, being elected President of the Royal Institute of British Architects 1870–73 and being awarded its Royal Gold Medal for Architecture in 1873. His reputation during his lifetime was largely as a safe establishment figure, and critical assessment has been less favourable more recently, particularly in comparison with his younger brother, the better known Matthew Digby Wyatt.
