An irreducible character of a finite group is called quasi -Steinberg character for a prime if it takes a nonzero value on every -regular element of . In this paper, we classify the quasi -Steinberg characters of Symmetric () and Alternating () groups and their double covers. In particular, an existence of a nonlinear quasi -Steinberg character of implies and of implies .
