Leixlip (Léim an Bhradáin in Irish) is a town in north-east County Kildare, Republic of Ireland, east of the midlands of Ireland. It is situated on the confluence of the River Liffey and the River Rye, on the border of the ancient kingdoms of Leinster and Brega. Its population of 14,676 (2006 Census) makes it the fourth largest town in Kildare and the 26th largest in the republic of Ireland, hosting both local workers, and those commuting to Dublin, which is around 15km distant. The placename comes from the Viking Lax Hlaup, which means "leap of the salmon". The name in Irish is also a direct reflection of this. Leixlip is home to facilities of Intel and Hewlett-Packard. It is also home of Arthur Guinness's first brewery where he brewed ales until he moved to St. James's Gate Brewery, Dublin in 1759 where he first brewed Guinness. Historically, it is the site of the famous Battle of Confey, in which the Viking King Sigtrygg Caech of Dublin defeated the Irish King of Leinster around the year 917.
