Ardmhor (Scottish Gaelic: Aird Mhòr) is a small village in the north east of the Isle of Barra in the Outer Hebrides, Scotland.

In 2002 a small ferry port was built in the village to serve a new ferry link between Barra and Eriskay as part of the Sound of Barra Integrated Transport Project.

A causeway had previously been built linking Eriskay to South Uist.

The daily service on the MV Loch Alainn has frequent sailings; the crossing takes approximately 40 minutes.

Note that the correct location for the port is as follows, rather than at Aird Mhidhinis as shown on some printed Ordnance Survey maps.
