Chōgei (ちょうげい) is a diesel-electric submarine of the Japan Maritime Self-Defense Force, and the fifth and final member of the Taigei class. Her name is written in kanji as "長鯨", literally meaning "giant whale", and this is the third use of the name, after the Meiji-era steamboat Chōgei Maru, and the Imperial Japanese Navy's Jingei-class submarine tender Chōgei.

Chōgei was laid down on 19 April 2022 at Mitsubishi Heavy Industries Kobe Shipyard as part of the JMSDF's Mid-Term Defense Program of 2021, and was launched on 4 October 2024 after being christened. After being fitted out and undergo various trials, the vessel is scheduled to be handed over to the Japan Maritime Self-Defense Force in March 2026.
