The Adams Park surface was deemed unplayable at an inspection on Saturday morning.
A statement on Wycombe's official website said: "Heavy rain overnight and throughout this morning led to referee Scott Mathieson holding a pitch inspection at 10.30am where he deemed the pitch unplayable.
"As always the players' safety is of paramount importance which is why the decision was taken."
A date for the rearranged game will be announced in due course.
