Llanfihangel-y-Pennant is a hamlet and wider, very sparsely populated community (which includes Abergynolwyn and Tal-y-llyn) in the Meirionnydd area of Gwynedd in Wales.

It is located in the foothills of Cadair Idris, and has a population of 402,[1] reducing to 339 at the 2011 Census.

In 1800, Mary Jones walked barefoot 26 miles (42 km) from the village to Bala to buy a Welsh Bible.
