NGC 1964 is a barred spiral galaxy in the constellation Lepus.[2] The galaxy lies 65 million light years away from Earth, meaning, given its apparent dimensions, NGC 1964 is approximately 150,000 light years across. At its center lies a supermassive black hole, with an estimated mass of 2.5 × 107 M☉.[4] The galaxy features two tightly wound inner spiral arms within a disk with high surface brightness and two outer, more open spiral arms that originate near the inner ring. The outer arms feature few small HII regions.[5]

NGC 1964 is the main galaxy in a group of galaxies, known as the NGC 1964 group, which also includes the galaxies NGC 1979, IC 2130 and IC 2137.[6]

Supernova SN 2021jad (Type Ia, mag. 12.9) was discovered in this galaxy in April 2021.[7]
