Miminegash Harbour is a small working harbour located in Miminegash, Prince Edward Island, on the island's western shore. It serves local fishing and recreational boating activity and is noted as a productive spot for striped bass fishing.

The harbour has faced infrastructure challenges in recent years, with federal funding being sought to assess and repair aging structures, including work on the southern breakwater.

The federal Department of Fisheries and Oceans has been collaborating with the Miminegash Harbour Authority to evaluate existing infrastructure and plan for the harbour's long-term needs.
