Unofficial Sentai Akibaranger (非公認戦隊アキバレンジャー, Hikōnin Sentai Akibarenjā) is a Japanese tokusatsu comedy drama based on the Super Sentai Series. It is not part of the official line up in Toei Company's Super Sentai franchise, but is instead a self-parody geared towards adults as opposed to a general audience for the mainstream series. The show aired on BS Asahi (TV Asahi's broadcast satellite channel) starting April 6, 2012, and Tokyo MX starting April 9, 2012.
A second season was officially announced in January 2013 at a teaser event tying in with the final appearances of the characters from Tokumei Sentai Go-Busters, featuring Masato Wada, who performs as main character Nobuo Akagi. The second season is titled Unofficial Sentai Akibaranger: Season Tsuu (非公認戦隊アキバレンジャー シーズン痛（ツー）, Hikōnin Sentai Akibaranger: Shīzun Tsū) and premiered on April 5, 2013.
