The Cummeragh River is a short waterway in County Kerry on the southwest coast of Ireland, flowing south-westerly for roughly 8.5 km before emptying into Lough Currane near the coastal village of Waterville. The river cuts through the Cummeragh River Bog Nature Reserve, a 45.55-hectare lowland blanket bog established as a protected area in 1984 and recognised as the most southerly intact example of its type in Ireland. The bog is almost completely encircled by the Cummeragh River and a tributary, and is state-owned by the National Parks and Wildlife Service.

The paddling character ranges from grade 2 to 3+ rapids in the upper and middle sections, transitioning to a final flat-water crossing of Lough Currane. The total paddling distance is approximately 3.8 km of moving water plus 1.4 km of flat water on the lough. The put-in is at Cahersavane Bridge (GPS 51.864305, -10.090835), with the launch point just upstream. The take-out is at the fishermen's car park beside Lough Currane (GPS 51.843417, -10.129674). The river is accessed via the N70 — turn into Waterville village and follow the local road running alongside Lough Currane. A small public car park off the local road also provides access.

No formal permit is required for kayaking, though paddlers are asked to respect private land and observe parking signage. Paddling is possible year-round, subject to water levels. Mobile signal can be patchy across the bog, so carrying a GPS-enabled map or a printed copy of OS Map No. 83 is advisable.

The nature reserve supports curlews nesting on the bog, and the two rivers bordering the reserve contain spawning beds for sea trout. The bog itself features a well-developed pattern of hummocks and pools with a mature vegetation cover. Anglers also use the river for salmon and sea trout fishing during the season, so paddlers should be aware of other river users, particularly around Cahersivane and Cummeragh Bridges, which are noted fishing access points.
