Abstract. The purpose of this paper is to introduce and study $\gamma$-$\beta$-connectedness in terms of $\gamma$-$\beta$-open sets [#!bmu!#] defined using an operator $\gamma$ due to Ogata [#!oga!#]. Several characterizations, basic properties and preservation theorems of $\gamma$-$\beta$-connectedness are obtained. The concepts like $\gamma$-$\beta$-component, $\gamma$-$\beta$-quasi-component and local $\gamma$-$\beta$ connectedness are also investigated.
