Summary: For paths $P_n$ {\it G. Chartrand, L. Nebesk\'{y}} and {\it P. Zhang} [Discuss. Math., Graph Theory 24, No. 1, 5--21 (2004; Zbl 1056.05053)] gave the exact value of $ac'(P_n)$ for $n\leq 8$, and showed that $ac'(P_n)\leq \binom {n-2}{2}+2$ for every positive integer $n$, where $ac'(P_n)$ denotes the nearly antipodal chromatic number of $P_n$. In this paper we determine the exact values of $ac'(P_n)$ for all even integers $n\geq 8$.
