Kamen Rider Decade (仮面ライダーディケイド, Kamen Raidā Dikeido, Masked Rider DCD) is the title of the first installment of the 2009 editions of the long-running Kamen Rider Series of tokusatsu dramas. Decade, as its title suggests, is the tenth of the Heisei Rider special anniversary Series, having begun with Kamen Rider Kuuga in 2000. It began broadcasting the week following the finale of Kamen Rider Kiva and was featured in Super Hero Time alongside the 2009 edition of the Super Sentai Series, Samurai Sentai Shinkenger and replaced by Tensou Sentai Goseiger. Kamen Rider Zi-O, the last Heisei era series of 2018-2019, acts as a spiritual sequel, where both Decade and Diend play prominent roles as re-occurring side characters who are directly involved in that series plotline.
