HD 4628 is a main sequence dwarf star in the constellation Pisces. It has a spectral classification of K2, giving it an orange-red hue and a slightly smaller mass and girth than our Sun. It lies at a distance of approximately 24 light years from us and has a relatively high proper motion. The apparent magnitude is just sufficient for this star to be viewed with the unaided eye.

No companion has yet been found in orbit around this star. In 1958 it was thought to have stellar companion that was also a flare star, but this was subsequently disproven. [Hartkopf & McAlister, 1984, "Binary stars unresolved by speckle interferometry", "Astronomical Society of the Pacific", vol. 96.]
