Palm distributions are critical in the study of point processes. In the present paper we focus on a point process $Φ$ defined as the superposition, i.e., sum, of two independent point processes, say $Φ= Φ_1 + Φ_2$, and we characterize its Palm distribution. In particular, we show that the Palm distribution of $Φ$ admits a simple mixture representation depending only on the Palm distribution of $Φ_j$, as $j=1, 2$, and the associated moment measures. Extensions to the superposition of multiple point processes, and higher order Palm distributions, are treated analogously.
