The concept of the incidence chromatic number of a graph was introduced by Brualdi and Massey (1993). They conjectured that every graph can be incidence colored with colors. In this paper, we calculate the incidence chromatic numbers of the complete -partite graphs and give the incidence chromatic number of three infinite families of
