Abererch, Welsh Afon-erch, is a small town and former independent municipality on the River Erch on the Lleyn Peninsula (Pen Llŷn) in County Gwynedd, Wales. The place belongs to the former Cantref Eifionydd. Since 1934 Abererch is incorporated at Llannor. It is a place where mostly Welsh is spoken. In Abererch there is a kindergarten, a primary school and a train station. The station is located on the railway line from the beach in the village and on to Pwllheli, the district capital. Originally the railway line was operated by the Aberystwyth and Welsh Coast Railways, a branch line of the Cambrian Railways (Llinell Cambria) and was connected to the network of the Great Western Railway. After nationalization, she was part of the London Midland region of British Railways, until she was privatized again as Cambrian Coast Railways. The station is unoccupied, trains stop here only as needed. According to the poetry collection Englynion y Beddeu ("The Stanzas of the Tombs"), the tomb of King Rhydderch Hael of Old Clut is said to be in Abererch. However, a localization has not been successful so far.
