Kamen Rider ZEZTZ (仮面ライダーゼッツ, Kamen Raidā Zettsu) is a Japanese tokusatsu television series, the 36th entry of Toei Company's Kamen Rider metaseries, and the seventh series to debut during the Reiwa period. The series debuted on September 7, 2025, joining No.1 Sentai Gozyuger and later, Super Space Sheriff Gavan Infinity and later, Kakusei Hunter Omegahorn in the Super Hero Time lineup after Kamen Rider Gavv's finale. The series concluded on August 30, 2026 and was succeeded by Kamen Rider MY-TH.
The overall themes of the series are dreams and spy technology. It is both the first Kamen Rider series to have a global simulcast alongside its domestic Japanese release and, to date, the final series to air alongside a Super Sentai series for the time being.
The second half of the series coincides with the 55th anniversary of the entire Kamen Rider franchise.
