Nagalit ang Buwan sa Haba ng Gabi (transl. The Moon Got Mad at the Long Night) is a 1983 Filipino drama film written, co-produced, and directed by Danny Zialcita. It depicts and tackles love affairs, homosexuality, and adultery.

The film revolves around the seemingly normal love polygon - Delza (Laurice Guillen), the long-suffering and problematic wife; Stella (Gloria Diaz), the mistress; and Miguel (Dindo Fernando), the adulterous husband. There are a few more cornerstones in this love polygon, like Dimitri (Eddie Garcia), Stella's husband who is gay, and Raul (Tommy Abuel), Delza's ex-boyfriend as well as some other characters that would make a huge connection to the story filled with fiascoes of marriage and affairs.

The film was digitally restored and remastered in high-definition by the ABS-CBN Film Restoration Project and Central Digital Lab. The restored version was premiered on November 17, 2016, at Trinoma Cinema 1.
