Connaught Tunnel, in the Selkirk Mountains under Rogers Pass on the Canadian Pacific Railway main line between Calgary, Alberta, and Revelstoke, British Columbia, at long was, at the time it was built, the longest railway tunnel in North America.

Dug under Mount Macdonald () to ease growing traffic experienced between 1910 and 1913, it replaced the dangerous Rogers Pass route.

It was named for the Governor General of Canada – Prince Arthur, Duke of Connaught – who in turn was named after the province of Connaught in Ireland.
