Lough Leane (/ˈleɪn/; from Irish Loch Léin 'lake of Léan', a personal name)[1] is the largest of the three lakes of Killarney, in County Kerry.

The lake takes its name from Léan Línfhiaclach, a character mentioned in the dindshenchas or place-lore tradition.

Archaeological evidence suggests the island has been mined since the time of the Bronze Age Beaker People.

To prevent further pollution causing a permanent change in the lake's ecosystem, a review of land use in the catchment area is being carried out.

[7] Lough Leane is a habitat for the critically endangered blunt-snouted Irish char (Salvelinus obtusus) and Killarney shad (Alosa killarnensis).
