Belturbet is a small town on the River Erne in County Cavan, situated at the head of the navigable river near the border with Northern Ireland.

By water, it serves as a key access point connecting the River Erne northward into Lough Erne and southward via the Shannon-Erne Waterway to Carrick-on-Shannon and the broader Irish inland waterway network.

Belturbet Marina, operated by Waterways Ireland, provides moorings on the waterway and serves as a practical base for cruising in either direction. Day boat and cruise hire are available locally.

The River Erne around Belturbet is also well regarded for pike fishing, with bank and boat angling accessible at multiple points above and below the town.
