Around the world, Gruber (Gruber , Грубер , גרובר ) is a rare epicene first name. The given name Gruber is characteristic of Austria, where it is quite a rare dominantly male, but infrequently female name, Italy, where it is a rare gender-neutral name, and Hungary. In absolute terms, it is commonest in Italy, Austria, and Peru. Much more prevalently, Gruber is the last name as well as the forename.
Gruber is also a name for the fictitious and mythical characters: Grover , the character on Sesame Street and Grover Underwood , the fictional character in Rick Riordan's Percy Jackson and the Olympians series, Percy Jackson & the Olympians.
