Weston Airport, also called Dublin Weston Airport, is a publicly licensed general aviation (GA) airport serving Dublin and its environs since the early 1930s. It is located between Leixlip, County Kildare, and Lucan, Dublin 8 NM west of Dublin. Its traffic is primarily private and commercial flight training as well as business/executive travel. It is the only general aviation airport in the greater Dublin region, and is home to one of Ireland's two approved training organisations for ab-initio professional pilot training.

Leixlip is a town in north-east County Kildare, Ireland. Its location on the confluence of the River Liffey and the Rye Water has marked it as a frontier town historically: on the border between the ancient kingdoms of Leinster and Brega, as an outpost of The Pale, and on Kildare's border with County Dublin. Leixlip was also a civil parish in the ancient barony of Salt North.
