Vanadium-52 is a radioisotope of the chemical element Vanadium, which, in addition to the element-specific 23 protons, has 29 neutrons in the atomic nucleus, resulting in the mass number 52.

The very short-lived, unstable and therefore radioactive nuclide, which can only be produced artificially, has no practical significance; The study of ⁵²V serves exclusively academic purposes.
