NGC 337 is a barred spiral galaxy in the constellation Cetus. Its velocity with respect to the cosmic microwave background is , which corresponds to a Hubble distance of . Additionally, 20 non-redshift measurements give a similar distance of .
It was discovered on September 10, 1785 by German-British astronomer William Herschel. It was described by John Dreyer as "pretty faint, large, extended, gradually a little brighter middle, 10th magnitude star 21 seconds of time to the east."
NGC 337 is considered as a Late-Type Morphology galaxy, with a Star Formation Rate (SFR) of 1.62 M⊙ yr⁻¹ and has a Star Formation Efficiency (sSFR) of -9.62.
