The 112m-long (367ft) Dutch-registered MV Flinterspirit became stuck on Flodday Mor Island on its way from Sweden to Belfast at about 22:45.
All 10 people on board were safe and well and the crew managed to successfully refloat the 4,500-tonne vessel at high tide at about 05:00.
RNLI lifeboats from Barra and Stornoway had escorted the vessel.
It will be inspected in Stornoway on Lewis before being allowed to continue its journey.
