Llangybi (English: Cybi's Church) is a village and former civil parish in the Eifionydd area of the Welsh county of Gwynedd, near Llanarmon.

"This parish, which derives its name from the dedication of its church to Saint Cybi, an eminent British saint, who flourished towards the close of the sixth century, is pleasantly situated in the south-western portion of the county, and nearly in the centre of the promontory which separates Cardigan bay from the bay of Carnarvon.

It is of very considerable extent, and the lands are mostly enclosed and in a good state of cultivation : the surrounding scenery is pleasingly diversified, comprising some fine views of the adjacent country, which abounds with varied and picturesque beauty.

[3] The lychgate is listed at Grade II[4] and a Celtic cross] in the churchyard, dating from the 7th or 9th century, is a Scheduled monument.
