MV Wolfe Islander IV is a hybrid ferry serving between Kingston, Ontario and Wolfe Island in the Great Lakes. It replaces the ferry MV Wolfe Islander III and brings 50% more capacity. Wolfe Islander IV was constructed alongside another ferry, Amherst Islander II, using the same hybrid technology.

Wolfe Islander IV is a Damen 9819 E3 built at the Damen Galați shipyard in Romania. After being handed over to the Ontario Ministry of Transportation in August 2021, it was originally anticipated to be brought into full-time service in mid 2022, but faced several delays due in part to crew shortages and incomplete docking infrastructure. The ferry eventually began full-time service on August 17, 2024, however, as of September 2025 it has faced two major incidents that have taken it out of service for multiple months to do repairs.
