Colonel Sir Joseph David Rodolphe Forget (December 10, 1861 – February 19, 1919) was a Canadian business investor, stockbroker, and politician.

His mother, Angele Limoges, was the half-sister of Sir Louis-Olivier Taillon, 8th Prime Minister of Quebec.

With wide-ranging business interests, one of his companies built the Manoir Richelieu hotel in 1899 at La Malbaie, Quebec.

In 1904, Forget was elected as a Conservative to the 10th Canadian Parliament for the Charlevoix riding, and he served for more than thirteen years.

Forget died in 1919 at the age of fifty-seven and was buried in the Roman Catholic Cimetière Notre-Dame-des-Neiges in Montreal.
