Route 437, also known as Cape Onion Road, is a 22.1adj=midNaNadj=mid north-south highway on the northern edge of the Great Northern Peninsula of Newfoundland in the Canadian province of Newfoundland and Labrador. It connects the communities of Cape Onion-Ship Cove and Raleigh, along with Pistolet Bay Provincial Park, with Route 436 (L'Anse aux Meadows Road) and St. Anthony.
Route 437 begins at an intersection with Route 436 a few kilometres northwest of St. Anthony. It immediately winds its way northwest along the coastline through rural areas for several kilometres to pass through Pistolet Bay Provincial Park. The highway now arrives at Raleigh, where it makes a sharp right turn at an intersection with Raleigh Spur Road, which provides access to downtown and the Burnt Cape Ecological Reserve. Route 437 now heads northeast along the coastline for several kilometres before entering Cape Onion-Ship Cove, where Route 437 ends at a fork in the road between two local roads, with one leading to Cape Onion and the other leading to Ship Cove.
