Power Rangers Lightspeed Rescue is an American television series and the eighth season of the Power Rangers franchise, based on the Super Sentai series Kyuukyuu Sentai GoGoFive.

It was the first incarnation of Power Rangers to have the Rangers identities to be known to the public from the outset, as opposed to previous incarnations where a Ranger's identity was to be kept secret, revealed only in extreme circumstances. The series was also the first in which the Rangers' powers, Zords, and weapons were entirely manmade and had no mystical or extraterrestrial origin whatsoever.

Lightspeed Rescue also had, for the first time, a Power Ranger with no Super Sentai counterpart in the Titanium Ranger, as there was no regular sixth Ranger in GoGo V. It is the last Saban Entertainment-produced Power Rangers series to feature the main villain from its Super Sentai counterpart, until the premiere of Power Rangers Samurai. The next series to feature the main villain from its Super Sentai counterpart would be the Disney-produced Power Rangers Mystic Force, which premiered six years later.
