Muslim .357 (or Magnum Muslim .357) is a 1986 Philippine action film directed by and starring Fernando Poe Jr. as an undercover officer of the Philippine Constabulary. The film was both a box-office and critical success, earning nominations from various award giving bodies in the Philippines, twice winning the Best Actor award for Poe's performance. This, along with Poe's earlier portrayal of a Muslim hero in Zamboanga (1966), endeared Poe even more to Muslim audiences who are known to be passionate about the outcome of Poe's movies story-wise.
