Charles James Fox Bennett (11 June 1793 in Shaftesbury, England – 5 December 1883) was a merchant and politician who successfully fought attempts to take Newfoundland into Canadian confederation.

Bennett was a successful businessman and one of the colony's richest residents with interests in the fisheries, distillery and brewery industry and shipbuilding.

His brother Thomas Bennett, a magistrate and member of Newfoundland's first House of Assembly, was a partner in the business.

In the 1860s, he led the Anti-Confederation Party opposing the proposals by Sir Frederick Carter to join Canada.

Bennet also commissioned extensive mineral surveys along the coasts, and in the 1860s developed the prosperous copper mine at Tilt Cove (Notre Dame Bay).
