Niederöblarn is a former municipality in the district of Liezen, in the Austrian state of Styria. It lies in the Ennstal, the valley of the Enns river, within the Liezen district of northwestern Styria.
Since the 2015 Styria municipal structural reform, Niederöblarn is no longer an independent municipality; it is now part of the municipality of Öblarn. The reform merged a number of small Styrian municipalities into larger administrative units.
