NGC 151 is a mid-sized barred spiral galaxy located in the constellation Cetus.

KAISIS observed the same galaxy and catalogued it as NGC 153, only for it later to be identified as NGC 151.{{cite web|url=http://cseligman.com/text/atlas/ngc1a.htm#151|title=New General Catalogue objects: NGC 150 - 199|author=Seligman, Courtney|website=cseligman.com|access-date=2021-02-12}}

The galaxy, viewed from almost face on, has several bright, blue, dusty spiral arms filled with active star formation. One noticeable feature of the galaxy is a large gap between the spiral arms.

Two supernovae have been observed in NGC 151. On 22 July 2011, PTF11iqb (type IIn, mag. 17.1){{cite journal|doi=10.1093/mnras/stv354|title=PTF11iqb: Cool supergiant mass-loss that bridges the gap between Type IIn and normal supernovae|year=2015|last1=Smith|first1=Nathan|last2=Mauerhan|first2=Jon C.|last3=Cenko|first3=S.
