Ballybeg (Irish: Baile Beag) is a largely working class district in Waterford, Ireland.

The area consists of four council housing estates - Ballybeg, Priory Lawn, Clonard Park and Ardmore Park, and a private housing estate, Glencarra.

[1] Ballybeg is accessed via the N25 junction outside the (now defunct) 'Waterford Crystal' factory, the N25 junction past the 'Cartamundi' (formerly Hasbro) games factory, and the Ballybeg Link Road off the Kilbarry road.

This area was reputedly home to a priory of the Knights Templar and later became the Irishtown of Waterford.

Ballybeg is served by a church (St. Saviour's), a primary school (St. Saviour's National School), two supermarkets, a takeaway, and a parish centre / sports hall.
