Liam Origin and Meaning

The name Liam is a boy's name of Irish origin meaning "resolute protection".

Liam is the top boys' name in the US, holding the Number One spot for the past eight years and also ranking as one of the most popular boys' names around the western world.

Liam originated as a short form of Uilliam, the Irish variation of William. William is an English name from Germanic roots that was brought to Ireland when the British fled England following the Norman Conquest. The Irish began using English names, including William, which led to the development of Uilliam and its short form, Liam.

Internationally, Liam is enjoying great popularity not only in the U.S. and its native Ireland, but in countries as diverse as Italy and Israel, Chile and Croatia. If you're looking for a boys' name that will easily translate across many languages and cultures, you can't do better than Liam.

Irish-born actor Liam Neeson was instrumental in driving Liam up the charts, as was former Oasis member Liam (born William) Gallagher, and, more recently, One Direction member Liam Payne. Celebrities who have chosen Liam for their sons include Tori Spelling, Calista Flockhart, Rod Stewart, Kevin Costner and Craig Ferguson.

Jaunty and richly textured, Liam holds solidly to the title of most popular boys' name starting with the letter L.
