Chwilog () is a village in Gwynedd, north Wales, and located on the Llŷn Peninsula. It is in the community of Llanystumdwy, near Criccieth, and in the medieval commote () of Eifionydd, named after a 5th-century ruler.

The name means 'abounding in beetles' and was perhaps transferred from an earlier name of the river (or a part of it).
