库奇鲸（学名：Kutchicetus），又名喀曲鲸，是4600万年前始新世早期的鲸鱼，能够行走及游泳。牠是鲸鱼从陆上哺乳动物演化的过渡性生物。牠的体型细小，与现今的水獭接近。

Kutchicetus ("Kutch whale") is an extinct genus of early whale of the family Remingtonocetidae that lived during Early-Middle Eocene (Lutetian and Ypresian) in what is now the coastal border of Pakistan and India (23°42′N 68°42′E / 23.7°N 68.7°E / 23.7; 68.7, paleocoordinates 6°00′N 61°48′E / 6.0°N 61.8°E / 6.0; 61.8). It is closely related to Andrewsiphius with which it was synonymized by Gingerich et al. 2001. Thewissen & Bajpai 2009 proposed a new clade, Andrewsiphiinae, for the two species. Later authors, however, still accept both as separate genera.
