"Day of the Dumpster" is the first episode of both the American tokusatsu television series Mighty Morphin Power Rangers and the Power Rangers franchise. It premiered on the Fox network on August 28, 1993 as part of its Fox Kids programming block, and was later released on VHS and DVD. A new re-version of the episode later aired on ABC on January 2, 2010, as part of ABC Kids. As with the first season's episodes, most of the scenes featuring the Rangers in morphed form, the Zords and the villains are taken from the Japanese tokusatsu series, Kyōryū Sentai Zyuranger, the 16th entry of the Power Rangers franchise's Japanese counterpart of origin, Super Sentai.

Mighty Morphin Power Rangers (MMPR) is an American superhero television series that premiered on August 28, 1993, on the Fox Kids programming block. It is the first entry of the Power Rangers franchise, and became a 1990s pop culture phenomenon along with a large line of toys, action figures, and other merchandise. The show adapted stock footage from the Japanese TV series Kyōryū Sentai Zyuranger (1992–1993), which was the 16th installment of Toei's Super Sentai franchise. The second and third seasons of the show drew elements and stock footage from Gosei Sentai Dairanger and Ninja Sentai Kakuranger, respectively, though the Zyuranger costumes were still used for the lead cast in these two seasons. Only the mecha and the Kiba Ranger costume from Dairanger were featured in the second season while only the Kakuranger mecha was featured in the third season, though the Kakuranger costumes were later used for the mini-series Mighty Morphin Alien Rangers. The series was produced by MMPR Productions and distributed by Saban Entertainment, while the show's merchandise was produced and distributed by Bandai Entertainment.
