The Hundred of Narberth was a hundred in Pembrokeshire, Wales. It was formed by the Act of Union of 1536 from parts of the pre-Norman cantrefs of Penfro (the commote of Coedrath) and Cantref Gwarthaf (the commote of Efelfre). It derives its Welsh name from the town and district of the same name, which means "(district) by the wood", (that is the forest of Coedrath). The hundred spanned the linguistic boundary, with the parishes of Velfrey being identified by George Owen as Welsh-speaking, and the southern coastal part being English-speaking, part of Little England beyond Wales.
