This is a list of Polish divisions in World War II. In contrast to Wikipedia's reasonably complete descriptions of U.S., British, and German divisions, only some Polish divisions have articles here, mostly because the detailed histories have either not been translated from Polish or have not been fully released from the official archives. (See Wikipedia:WikiProject Countering systemic bias).
