Tenchu Z (天誅 千乱 Tenchu Senran?) is an action-adventure stealth video game developed by K2 LLC and published by From Software for the Xbox 360 in 2006.

It is different from previous games in the series in that the player creates their own ninja characters, then builds up their skills as they play through the game rather than choosing from a small selection of pre-made characters, as they take orders from the series’ previous main male character, Rikimaru. It also features four-player cooperative play through Xbox Live.
