Liptovská Mara (Slovak pronunciation: [ˈliptɔwskaː ˈmara]) is a reservoir in northern Slovakia, on the Váh river near Liptovský Mikuláš, in the Liptov region.
During construction, thirteen villages were inundated and a major railway and road relocated.
The main purpose of this dam is to prevent floods, although it also generates electricity.
The reconstructed Celtic oppidum Havránok is situated on a hill above the dam.
