A $(p,q)$ graph $G$ is said to have a $k$-odd mean labeling $(k \ge 1)$ if there exists an injection $f : V \to \{0, 1, 2, \ldots, 2k + 2q - 3\}$ such that the induced map $f^*$ defined on $E$ by $f^*(uv) = \left\lceil \frac{f(u)+f(v)}{2}\right\rceil$ is a bijection from $E$ to $\{2k - 1, 2k + 1, 2k + 3, \ldots, 2 k + 2q - 3\}$. A graph that admits $k$-odd mean labeling is called $k$-odd mean graph. In this paper, we investigate $k$-odd mean labeling of prism $C_m \times P_n$.
