NGC 1664 is an open cluster in the constellation of Auriga. It contains stars with a total of around 640 solar masses with a tidal radius of 43 ly (13.2 pc).

NGC 1664 is a somewhat young cluster, with an age of 675 ± 50 Myr, and is dynamically relaxed. It is located some 4,200 light-years away, or about 1.3 kpc. Born outside of the solar circle, it orbits the center of the Milky Way every 244 million years.
