Ballsbridge is an affluent neighbourhood of the city of Dublin, the capital of Ireland. The area is largely situated north and west of a three-arch stone bridge across the River Dodder, on the south side of the city. The sign on the bridge still proclaims it as "Ball's Bridge", in recognition of the fact that the original bridge on that location was built and owned by the Ball family, a well-known Dublin merchant family in the 1500s and the 1600s. The current bridge was built in 1791.

The River Dodder is one of the three main rivers in Dublin, Ireland, the others being the Liffey, of which the Dodder is the largest tributary, and the Tolka.
