In this paper we give a realization of crystal bases for quantum affine algebras
using some new combinatorial objects which we call the Young walls. The Young
walls consist of colored blocks with various shapes that are built on a given
ground-state wall and can be viewed as generalizations of Young diagrams. The
rules for building Young walls and the action of Kashiwara operators are given
