《TSUKI》（月亮）为日本歌手安室奈美惠于2014年1月29日发行的第41张单曲。

Tsuki(突き) is the Japanese word for "thrust", coming from the verb tsuku(突く), meaning "to thrust". The second syllable is accented, with Japanese's unvoiced vowels making it pronounced almost like "ski" (but preceded by a "t" sound). In Japanese martial arts and Okinawan martial arts, tsuki is used to refer to various thrusting techniques.
