NGC 78 is a pair of galaxies in the constellation Pisces. NGC 78A, which is the more southern galaxy, is a barred spiral galaxy. NGC 78B, which is the more northern galaxy, is an elliptical galaxy.{{cite simbad|title=NGC 78B|access-date=6 September 2017}} Although the designations NGC 78A and 78B are used today, the designation NGC 78 was formerly used mainly for the northern galaxy.
