Naturally occurring rhenium (75Re) is 37.4% Re, which is stable (although it is predicted to decay), and 62.6% Re, which is unstable but has a very long half-life (4.12×10 years). Among elements with a known stable isotope, only indium and tellurium similarly occur with a stable isotope in lower abundance than the long-lived radioactive isotope.
There are 36 other unstable isotopes recognized, the longest-lived of which are Re with a half-life of 70 days, Re with a half-life of 38 days, Re with a half-life of 3.7186 days, Re with a half-life of 64.0 hours, and Re with a half-life of 24.3 hours. There are also numerous isomers, the longest-lived of which are Re with a half-life of 200,000 years and Re with a half-life of 177.25 days. All others have half-lives less than a day.

- Re – Excited nuclear isomer.
- ( ) – Uncertainty (1σ) is given in concise form in parentheses after the corresponding last digits.
- # – Atomic mass marked #: value and uncertainty derived not from purely experimental data, but at least partly from trends from the Mass Surface (TMS).
- Bold half-life – nearly stable, half-life longer than age of universe.
- ^ # – Values marked # are not purely derived from experimental data, but at least partly from trends of neighboring nuclides (TNN).

Modes of decay:
EC: Electron capture IT: Isomeric transition
p: Proton emission - Bold italics symbol as daughter – Daughter product is nearly stable.
- Bold symbol as daughter – Daughter product is stable.
- ( ) spin value – Indicates spin with weak assignment arguments.
- Believed to undergo α decay to Ta
- Theoretically capable of β decay to Os
- primordial radionuclide
- Used in rhenium–osmium dating
- Can undergo Bound-state β decay with a half-life of 32.9 years when fully ionized
- Theorized to also undergo α decay to Ta
