It was discovered by William Herschel on March 18, 1790.[3] The galaxy is seen edge-on and appears to be slightly warped. It has a small bulge.[4] It is a member of the NGC 3610 galaxy group.[5] Members of the group that lie at a smaller projected distance from NGC 3669 include NGC 3674 and NGC 3683A 40′–50′ to the south and southeast and NGC 3613 and NGC 3619 40′–50′ to the west.
