The IJN North American Task Force (遣米支隊, Kenbei Shitai) was an Imperial Japanese Navy fleet.

In accordance with the Anglo-Japanese Alliance, the fleet defended the West Coast of Canada as well as Allied shipping in the Pacific during World War I.

A few ships were built or bought by the fledgling Canadian Navy but the decision was unpopular in Canada and contributed to the downfall of the Laurier government.

The Royal Navy decided to concentrate on the Atlantic theatre with the defence of Canada's west coast left to its ally, Imperial Japan.

"[7] Also on British request, the Japanese navy sent one or two cruisers from Vladivostok to Vancouver to assist in the transport of gold bullion.
