'''NGC 157''' (MCG -2-2-56)是[[鲸鱼座]]的一個[[星系]]。[[星等]]為10.4，[[赤經]]為34分46.4秒，[[赤緯]]為-8°23'46"。

1783年12月13日，[[弗里德里希·威廉·赫歇爾]]發現NGC 157。

NGC 157星系已經發生過兩次[[超新星]]事件。第一顆超新星2009em於2009年5月5日被發現，位於星系核心以西約34″、以南約10″處<ref name=Monard_2009/>，被確定為一顆Ic型超新星<ref name=Navasardyan_Benetti_2009/>。

2022年5月5日，NGC 157中觀測到Ic型超新星SN 2022jli，峰值星等達到14.4等<ref name=TNS_2023/>。
