The N19 road is a national primary road in Ireland, connecting from the N18 Limerick–Ennis–Galway road to Shannon Airport. It forms part of European route E20.

The route in its current form consists mostly of a dual-carriageway passing around Shannon Town, which starts at an interchange near Hurlers Cross on the N18 road. The dual-carriageway ends on the far side of Shannon Town at the Shannon Free Zone industrial estate, and proceeds as a two lane road to the airport.

Prior to the opening of this new dual-carriageway route in 2004, the route ran along a two-lane road through Shannon town centre itself. A junction without flyovers connected to what was then the end of the dual-carriageway section of the N18 (the dual-carriageway on that route now continues to Galway as a motorway as of September 2017).

Shannon Town can still be accessed from the N18 by use of the remaining portions of this road (connecting only as a slip road from the Limerick direction), as well as a new local link road from a new interchange at Hurler's Cross. The N19 no longer serves Shannon Town for most purposes, apart from the industrial estate.
