The Eonish Slipway is a free, roadside boat launch on the northern shore of the Eonish basin, part of the Lough Oughter complex in County Cavan, located approximately 4 km north-east of Killashandra off the Killashandra to Milltown road.

It provides anglers with direct water access to a productive fishery known for bream, roach, hybrids, tench, perch, and pike.

The northern shore of the Eonish basin runs to depths of 3–5 metres, shallowing at the eastern and western ends, making boat access particularly useful for reaching productive deeper water.

Additional launch options in the area include a sandy point on the southern shoreline, though vehicle access there requires prior arrangement with Coillte.

The slipway is well suited to anglers bringing their own boats for pre-baiting and fishing the wider Lough Oughter system.
