The existence, uniqueness, and sufficient conditions for stability in distribution of mild solutions to stochastic partial differential delay equations with jumps are presented. The principle technique of our investigation is to construct a proper approximating strong solution system and carry out a limiting type of argument to pass on stability of strong solutions to mild ones. As a consequence, stability results of some results are generalized to cover a class of much more general stochastic partial differential delay equations with jumps in infinite dimensions. Lastly, one example is presented to demonstrate the effectiveness of our theory.
