NGC 3241 is a spiral galaxy in the constellation of Antlia. Its velocity with respect to the cosmic microwave background is , which corresponds to a Hubble distance of . However, eight non-redshift measurements give a closer mean distance of . It was discovered by British astronomer John Herschel on 16 February 1836.
NGC 3241 has a possible active galactic nucleus, i.e. it has a compact region at the center of its galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.
