Llangynog (Welsh pronunciation; grid reference ) is a village and community at the confluence of the Afon Eirth and the Afon Tanat at the foot of the Berwyn range in north Powys (previously Montgomeryshire), Wales.
It lies at the foot of the Milltir Cerrig mountain pass on the B4391 road, which runs between Llan Ffestiniog and Llanfyllin (though the B4391 road number 'disappears' between the western end of Llyn Celyn and Bala).
It is surrounded by mountains including Craig Rhiwarth and is a popular base for walkers. Llangynog has a down-hill mountain bike course, and a crown green bowling club, who play in the Oswestry League.
It was the western terminus of the Tanat Valley Light Railway (Llynclys - Llangynog) (15 miles); it opened on 5 January 1904 and closed (passenger traffic) in 1951.
