Llanfair Caereinion is a small town and community in Montgomeryshire, Powys, Wales upon the River Banwy (also known as the River Einion), around 8 miles west of Welshpool. Its name is a combination of Welsh llan "church" + Mair "Mary" and caer "fort" + Einion, a personal name, meaning "the church of Mary [at] the fort of Einion".
In 2011 the ward had a population of 1,810. The town is built upon the site of an old Roman fort. Llanfair is most famous for being a terminus of the Welshpool and Llanfair Light Railway. The site of the Battle of Maes Moydog is nearby.
In 1758 the town was almost completely wiped out by the Great Fire which was so intense and devastating it was reported in the London Press.
