NGC 3925 is a barred[2] lenticular galaxy[3][2] and a ring galaxy[2] located about 370 million light-years away[3] in the constellation Leo. It was discovered by astronomer Heinrich d'Arrest on February 19, 1863.[4]

NGC 3925 is classified as a "PAS galaxy" because it contains mostly old stars, with no observable star formation activity. NGC 3925 is also a member of the Coma Supercluster.[5]
