Campbellford is an unincorporated place and former town in Northumberland County, Ontario, Canada, in the township municipality of Trent Hills.

About 70 years earlier, "the British government gave two brothers, Lieutenant-Colonel Robert Campbell and Major David Campbell, 1800 acres of land to settle in an area named for the Duke of Northumberland's wife Lady Elizabeth Seymour" (Trent Hills Visitors Guide, 2009, p. 13).

[2] In the summer, Campbellford's population swells with tourists taking advantage of the local lakes and waterways, trails, and camping areas.

Ferris Provincial Park is located on the Trent River a short distance south of Campbellford.

[citation needed] The town has a 27 ft (8.2 m) high statue of a toonie, which was designed by local artist Brent Townsend.
