In this paper by using the lacunary sequence and Orlicz function ϕ, we introduce a new concept of lacunary statistically ϕ-convergence, as a generalization of the statistically ϕ-convergence and ϕ-convergence. Based on this concepts, introduce a new sequence space Sθ-ϕ and investigate some of its basic properties. Also studied some inclusion relations.
