Bont Goch (also known as Bontgoch or Elerch) is a village in Ceredigion, Wales, 2 miles (3.2 km) northeast of Aberystwyth. With Talybont, it is in the community of Ceulanamaesmawr. The historic name was Elerch (the Welsh word for 'swan'; also recorded as a male personal name), which may be related to the name of the river Leri which flows through the area. The modern name Bontgoch in Welsh means "the red bridge".
