Thomas Clement Thompson (1780 – 11 February 1857) was an Irish artist and a founder member of the Royal Hibernian Academy.

Some time between 1803 and 1809, he changed tack to specialise in large-scale portraiture, although he did paint some landscapes.

By around 1817 he had moved from the successful studio he had established in Dublin to a new studio in London and was exhibiting at the Royal Academy, an institution at whose exhibitions he regularly featured until 1847.

An elected founder member of the Royal Hibernian Academy, he also exhibited there on occasion between 1826–52.

[1][2] Thompson moved his home from London to Cheltenham in 1848.
