The name Walden is a boy's name of German origin meaning "valley of the Welsh". Walden and is often added to lists like Unique Baby Boy Names and discussed in our forums with posts like "Sibset Makeover Game! Boys".
From the experts:
Walden is a recent entrant to the en-ending boys' names trend, a name that summons up placid images of Thoreau's two-year stay contemplating nature near Walden Pond.
A quite different image came into being when Walden was chosen as the name for Ashton Kutcher's character in "Two and a Half Men"--internet billionaire Walden Schmidt. It is also a Harry Potter name, via wizard Walden Macnair.
