Boduan is a village in Gwynedd, Wales, about 4 miles from Pwllheli. It is in the historic county of Caernarfonshire. It was due to host the National Eisteddfod in 2021[1] but due to the COVID-19 pandemic, instead it hosted the 2023 edition.
Garn Boduan, a hillfort built soon after Roman occupation, is located in the village.[2] Plas Boduan is an 18th century Grade II listed house, set in a park dating from the 19th century which is designated Grade II on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales.
