In this paper we prove an infinite-dimensional version of Sard's theorem forFr\'{e}chet manifolds.  Let $ M $ and $ N $ be bounded Fr\'{e}chet manifolds such that the topologiesof their model Fr\'{e}chet spaces are defined by metrics with absolutely convexballs.  Let $ f: M \rightarrow N $ be an $ MC^k$-Lipschitz-Fredholm map with $ k >\max \lbrace {\Ind f,0} \rbrace $. Then the set of regular values of $ f $ isresidual in $ N $.
