In this work, we prove best proximity point theorems for $\gamma$-contractions with conditions the weak P-property in non-Archimedean Menger probabilistic metric spaces. We give the notion of $\gamma$- proximal contractions of first and second type in non-Archimedean Menger probabilistic metric spaces and also we establish best proximity point theorems for these proximal contractions. Lastly, we complete our study by giving examples that support our results.
