Barry's Bay is a community in the township of Madawaska Valley, Ontario, Canada, located two hours west of Ottawa on the shores of Kamaniskeg Lake, with a 2021 population of 1,084.

[1] The Algonquin people named the area Kuaenash Ne-ishing, meaning beautiful bay.

[3] By the late 1850s, the authorities of Upper Canada looked to expand colonization in this region by building the Opeongo Line, a series of roads extending westward from Renfrew.

The community dedicated a park and monument to honour the construction of the Canadian Avro CF-105 Arrow and its chief test pilot, local resident Janusz Żurakowski.

Barry's Bay is the site of Our Lady Seat of Wisdom College (OLSWC), an accredited Catholic liberal arts post-secondary institution established in 2000.
