Mila 18 is a historical novel by Leon Uris set in German-occupied Warsaw, Poland, before and during World War II. Mila 18 debuted at #7 on The New York Times Best Seller list and peaked at #2 in August 1961. Leon Uris's work, based on real events, covers the Nazi occupation of Poland and the atrocities of systematically dehumanising and eliminating the Jewish people of Poland. The name "Mila 18" is taken from the headquarters bunker of Jewish resistance fighters underneath the building at ulica Miła 18. The term ghetto takes on a clearer meaning as the courageous Jewish leaders fight a losing battle against not only the Nazis and their henchmen, but also profiteers and collaborators among themselves. Eventually, as the ghetto is reduced to rubble, a few courageous individuals with few weapons and no outside help assume command of ghetto defence, form a makeshift army and make a stand.

Leon Marcus Uris was an American author of historical fiction who wrote many bestselling books including Exodus and Trinity.
