The Low Tatras or Low Tatra (Slovak: Nízke Tatry) is a mountain range of the Inner Western Carpathians in central Slovakia.
It is located south of the Tatras proper, from which it is separated by the valleys of the Váh and Poprad rivers (the Liptov-Spiš abasement). The valley formed by the Hron River is situated south of the Low Tatras range. The ridge runs west-eastwards and is about 80 km long.
The Čertovica pass divides the range into two parts. The highest peaks of the Low Tatras are located in its western part. Ďumbier is the highest mountain at 2,042 m AMSL.
