We define a natural ordering on the power set  P(Q) of any finite partial order Q, and we characterize those partial orders Q for which  P(Q) is a distributive lattice under that ordering.

 Keywords: partial order, chain, linear order, antichain, power set, power-ordered set, distributive lattice, anti-automorphism.
