An extremely massive star, typically many times larger than our Sun, often found in the early universe or in dense star-forming regions.
In astrophysics, a star with a mass significantly exceeding that of typical massive stars (often >100 solar masses), which may have unique evolutionary paths, including potential direct collapse to black holes without a supernova.

FAQ
Frequently Asked Questions
No, the Sun is a low-mass star (1 solar mass). Supermassive stars are over 100 times more massive.
They are extremely rare and short-lived, so none exist in our local cosmic neighbourhood. They are primarily studied in distant, early galaxies or through simulations.
It may end its life in a pair-instability supernova (completely destroying itself) or directly collapse into a black hole, depending on its exact mass and composition.
A supermassive star is a living, fusion-powered stellar object. A supermassive black hole is the dense remnant at the centre of galaxies, formed after such a star (or many stars) has died and collapsed.
An extremely massive star, typically many times larger than our Sun, often found in the early universe or in dense star-forming regions.
