Mighty Morphin Power Rangers (abbreviated as MMPR) is an American live-action television series, created for the American market, based on the 16th installment of the Japanese Super Sentai franchise, Kyōryū Sentai Zyuranger. The show and its related merchandise both saw unbridled overnight success, catapulting into pop culture in mere months. Under the original name Mighty Morphin Power Rangers, the series ran from 1993 to 1995 and spawned a feature film, Mighty Morphin Power Rangers: The Movie.

The second and third seasons drew on footage and elements from the Super Sentai series Gosei Sentai Dairanger and Ninja Sentai Kakuranger respectively, though the Zyuranger costumes were still used extensively; the main five Dairanger suits were never used at all, as only the Kiba Ranger suit was used for the White Power Ranger, while the five Kakuranger suits were used in the mini series Mighty Morphin Alien Rangers. The series was produced by MMPR Productions and distributed by Saban Entertainment, and aired on Fox Kids.

In 1996, the Mighty Morphin label was retired as the series would follow in the footsteps of Super Sentai, changing its name, cast and plot every year; thus the Power Rangers franchise was born. Power Rangers still runs in this format to this day, though currently the majority of post-MMPR series are not spin-offs in the traditional sense.
