Mount Macdonald is a mountain peak located in the Selkirk Mountains of British Columbia, Canada, immediately east of Rogers Pass in Glacier National Park. It is notable as the location of the Canadian Pacific Railway's Connaught and Mount Macdonald Tunnels. At 14.7 km, the Mount Macdonald tunnel is the longest railway tunnel in the western hemisphere.^{[citation needed]}

The original name of the peak was Mount Carroll (for a member of the CPR engineering team under A. B. Rogers^[2]), but was renamed to honor the first Prime Minister of Canada, Sir John A. Macdonald, by a Privy Council Order in Council #551 on 4 April 1887.^[2]
