Llanybydder (Welsh pronunciation: [ˌɬanəˈbəðɛr], formerly spelt Llanybyther, is a market town and community straddling the River Teifi in Carmarthenshire, West Wales.

Llanybydder is situated around 5 miles (8 km) southwest of Lampeter where the University of Wales Trinity Saint David is located.

Highmead, formerly the country mansion Dolau Mawr, built in 1777,[5] was most recently a centre of religious studies for the Muslim faith but is unoccupied as of early 2017.

The cost of repairs to a little-used rural line was deemed prohibitive, and although a limited service continued running from Carmarthen to Tregaron for another few months this was the era of the Beeching Axe.

As of October 2012[update], Dunbia (Dungannon Meats) was the largest business in Llanybydder, an abattoir, providing around 650 jobs.

Other businesses include cafes, farmers' co-operatives, a post office, a solicitor's practice, and a hotel in the village square.

It processed in excess of 5 million litres a year of fresh milk and operated distribution depots in Aberystwyth and Carmarthen.

It had six refrigerated lorries delivering to a total of 50 milkmen throughout West Wales together with schools, hospitals and other catering establishments.
