Nantmor is a hamlet which lies about 1½ miles to the south of the village of Beddgelert in Gwynedd, North Wales.
The current spelling of the name Nantmor is more modern - most old documents from the 16th to the 18th century record the name as Nanmor, although the Ordnance Survey map of 1558 records the name "Nant-y-mor."
