Hamilton Thomas Carlton Plantagenet MacCarthy RCA (28 July 1846 – 24 October 1939) was one of the earliest masters of monumental bronze sculpture in Canada.

[1] He is known for his historical sculptures, in particular his Pierre Dugua, Sieur de Mons at Annapolis Royal, Nova Scotia (1904)[2] as well as Samuel de Champlain overlooking Parliament Hill on Nepean Point, Ottawa (1915), next to the National Gallery of Canada.

He contributed to the Great Exhibition a group of a deer hunt, consisting of a Scottish huntsman about to blow his horn, with a felled stag and two dogs 'executed in silver for ornamental purposes'.

Their son, Hamilton P MacCarthy, was also a sculptor and he exhibited portraiture and ideal works at the Royal Academy between 1875 and 1884.

He worked with Dominion carver Cléophas Soucy on the figures for the Parliament Buildings including the lions at the entrance.

In the 1990s after lobbying by Indigenous people, the scout was removed from the sculpture's platform, renamed, and relocated as a statue in its own right to Major's Hill Park.
