John Egan (November 11, 1811 – July 11, 1857) was an Irish-Canadian businessman and political figure in the Ottawa region.

Egan was one of four men to finance the construction of the first flour and sawmill in Aylmer in 1839, and in partnership with Joseph Aumond, he founded the Union Forwarding Company in 1845.

He bought James Wadsworth's farm at the ‘Fifth Chute’ on the Bonnechere in 1838, which he later developed into the village of Eganville, Ontario.

He built dams and timber slides along the Bonnechere River and employed thousands of men through lumber camps and transportation.

Thanks to Egan's interest in red pine and business investments, the surrounding area would become a hub for lumber activity with Eganville at the centre.
