Menzies Bay is a large bay adjoining Seymour Narrows and Quadra Island north of Campbell River on Vancouver Island. It was once considered in 1872 as a crossing point to Vancouver Island for the Canadian Pacific Railway from Sonora Island and Bute Inlet in that project's quest for a transcontinental line. The bay was the site of a Bloedel, Stewart and Welch railroad logging camp in the 1930s, and adjacent to Ripple Rock.
There is a private campsite on the beach.
