The Parish of Julianstown is situated in the Barony of Lower Duleek and County Meath, and the parish is part of the Roman Catholic Union of Stamullen. Julianstown is significant in that it contains a bridge across the river Nanny on the road between Dublin and Belfast. One of the earliest mentions of Julianstown commemorates the Battle of Julianstown in 1641, which took place near the bridge. Indeed, there is a commemorative plaque on the bridge erected by Billy Butlin in the 1960s. Towards the south of the village is the smaller river Bradan (), which flows into the sea at Mosney.
