  Using the first cohomology from the mirror Heisenberg-Virasoro algebra to the
twisted Heisenberg algebra (as the mirror Heisenberg-Virasoro algebra-module),
in this paper we determined the derivations on the mirror Heisenberg-Virasoro
algebra. Based on this result, we proved that any 2-local derivation on the
mirror Heisenberg-Virasoro algebra is a derivation.
