The only name that the Grinch is ever called is simply "The Grinch".

The Grinch is the villain in Dr. Seuss's famous Christmas book "How the Grinch Stole Christmas." He is a grouchy creature who despises Christmas and sets out to ruin it for the Whos of Whoville.

"The Grinch" is his only known name.

He is sometimes called "Mr Grinch". Which may imply that "Grinch" is a surname. If it is, we actually are not told his full name.

In "The Grinch Who Stole Christmas" everything about the Grinch is bad When the Grinch breathes even his breath appears ugly. Like his complexion, the Grinch's breath is green.
