The River Laune (/ln/; Irish: An Leamhain) is a river in County Kerry, Ireland which flows from Lough Leane (sometimes written as Lough Lein), one of the Lakes of Killarney, through the town of Killorglin, and empties into the sea, first at Castlemaine harbour beside the river Maine and then out through Dingle Bay. The Laune is well known for salmon and trout fishing.

The river Laune is 14 miles (23 km) long and combined with the River Flesk 28.25 miles (45.46 km), which feeds Lough Leane, has a total length of 42.25 miles (67.99 km). It has a mean flow rate of 43 m³/s.

The River Laune, flows approximately 20 km to drain Killarney’s Lough Leane into the sea at Castlemaine Harbour. The Laune carries most of the rainfall from the MacGillycuddy Reeks, Ireland’s highest mountain range. Many streams on the south side of the Reeks drain into Killarney’s Upper Lake before filtering down to Lough Leane. As the River Laune drains Lough Leane to the sea, it is fed by two rivers running north from the Reeks, the River Loe from the Gap of Dunloe and the Gaddagh River from the heart of the Reeks. Another tributary, the Cottoners River, carries rainwater from the west of the Reeks. On the southern side of the bridge, a low embankment runs upstream for about 1 km towards Killarney. This is part of over 40 km of embankments that prevent the sea from flooding low-lying land around Castlemaine Harbour. These embankments exist due to Napoleon’s dominance in Europe around the year 1808. The British government were looking for alternative sources of hemp to make sailcloth for their navy to defend against a possible invasion.

If the bogs of Ireland could be drained then they could be used to grow this raw material without impacting on the existing agricultural output of the country. In 1811-1812 Alexander Nimmo surveyed and mapped over 76,000 acres (30,700 ha) of land on the Iveragh Peninsula for the Bogs Commission. Over 17,000 acres (7,000 ha) of this were on the sea shore area of the Laune River, Lower Maine River and Castlemaine Harbour. These stone and earthen banks still prevent high tides flooding much of this land. The banks vary from 1 m to over 5 m in height. Sluice gates allow water drain out at low tide and prevent rising tides from flooding the land. The banks run from the townland of Tullig near Cromane, to Killorglin, part way up the Laune, around the area of Callinafercy, up both sides of the Maine River and along the north side of Castlemaine Harbour, part way to Inch. Various major repairs are evident where large rocks and concrete have replaced the stone and earth, although much of the original banks are still intact.
