We study the regularity of symbolic powers of square-free monomial ideals. We give a sharp upper bound of regularity of symbolic power of I, where I is the Stanley-Reisner ideal of a simplicial complex. In addition, we obtain a general linear  upper bound reg(I^{(n)}) in case I is the edge ideal of a simple graph.
