Irish diminutive of William
"resolute protection"

Liam Origin and Meaning

The name Liam is a girl's name meaning "resolute protection".

A tiny percentage -- a tenth of one percent -- of babies named Liam in the US are girls. But Liam has been so popular for baby boys for so long, not only in the US but around the western world, that it's hard to imagine it truly becoming a unisex name.

Still, there are an increasing number of little girls named Noah and James every year, so as Liam's popularity for boys starts to fade, it may drift over to the female side.
