Abstract. We construct Green-Schwarz (GS) light-cone closed superstring theory from type IIB matrix model. A light-cone string action is derived from two dimensional N = 8 U(n) noncommutative Yang-Mills (NCYM) by identifying noncommutative scale with the inverse of string scale. Supersymmetry transformation for the light-cone gauge action is also derived from supersymmetry transformation for IIB matrix model. By identifying the physical states and vertex operators, string theory is perturbatively reproduced.
