V533 Herculis was a nova visible to the naked eye, which occurred in 1963 in the constellation of Hercules.

Both reported it to be a 4th magnitude star.

Subsequent examination of pre-discovery images, taken by the Baker-Nunn satellite tracking group at the Tokyo Observatory, showed that the star had begun its nova event as early as 18:36 UT on 26 January 1963, when it had a magnitude of 8. It had attained its peak brightness, magnitude 3, by 17:38 UT on 30 January 1968. Thorstensen and Taylor analysed spectra of the star in its quiescent state, and concluded that it is a non-eclipsing SW Sextantis variable, implying that the donor star is a red dwarf. Knigge derived a mass of , and a radius of , for the donor star.

Both were taken with [[H-alpha|Hα filters, left at the William Herschel Telescope, and right with the Nordic Optical Telescope. Santamaria et al. obtained similar results by comparing images of the shell taken in 1993 and 2018. They found that by 2018 the slightly elliptical shell had major and minor axis of 16.8×15.2 arc seconds, and it was expanding at a rate of 0.152×0.139 arc seconds per year, implying a physical expansion rate of 850×770 km/sec.
