Tensou Sentai Goseiger (天装戦隊ゴセイジャー, Tensō Sentai Goseijā, Heavenly Armament Squadron Goseiger) is the title of Toei Company's 34th entry in its long-running Super Sentai franchise. It follows an angelic motif as well as a trading card theme. It joined Kamen Rider W, and later Kamen Rider OOO, as a program featured in TV Asahi's Super Hero Time programming block. It aired from February 14, 2010 to February 6, 2011, replacing Samurai Sentai Shinkenger and was replaced by Kaizoku Sentai Gokaiger. The series ties in with the arcade game Super Sentai Battle: Dice-O, with the characters using cards resembling Carddass cards used in the game to transform and access various weapons, similar to the concept of Kamen Rider Decade and its link to Kamen Rider Battle: Ganbaride. Goseiger's footage was later used for the 2013 Power Rangers series Power Rangers Megaforce and its second season Super Megaforce.

The cast and characters were revealed at an event at Tokyo Dome City on January 30 and 31, 2010. The protagonists also had a cameo appearance in the film, Samurai Sentai Shinkenger vs. Go-onger: GinmakuBang!!.

Tensou Sentai Goseiger premiered in South Korea in July 2011 as Power Rangers Miracle Force. A June 2012 press release has revealed that the 2013 series, Power Rangers Megaforce, would adapt Goseiger (to the extent of re-using the names Tensou, Gosei, and Warstar).

The phrase "Descent!" (降臨!, Kōrin!) is utilized in the promotional materials for the series.
