Madoc is a township in Hastings County in Eastern Ontario, Canada.

The township was named after Welsh prince Madoc ap Owain Gwynedd, credited by some with discovering North America in 1170.

[3] The township of Madoc comprises several villages and hamlets, including communities such as Allen, Bannockburn, Cooper, Eldorado, Fox Corners, Hazzards Corners, Keller Bridge, Rimington, and Empey.

Mills and ironworks gave initial stimulus to the community of Madoc.

[5] Eldorado, 6 miles north of Madoc, was the site of Ontario's first gold rush on 18 August 1866 by Marcus Powell and William Berryman (or Nicholas Snider).
