#### QUESTION

Is it possible to castle while checkmate?



I can think of two questions you might be meaning to ask, given the wording of your question. Maybe neither of these is what you're after, but just in case:

1. Is it possible to castle out of check or even checkmate? Here the answer is no. If your king is in check, then castling is not a legal move.

2. Is it possible to castle while checkmating your opponent? Here the answer is yes, it is possible, though it does not happen often. For instance, the game Ed.Lasker-Thomas (1912), with its famous queen sacrifice and king hunt, could have finished with a castling mate:
