Wikipedia says that red dwarfs are small (no more than 40% of a solar mass) main-sequence stars.
Ooh, here's an interesting tidbit:

As red dwarfs are fully convective, helium does not accumulate at the
core and, compared to larger stars such as the Sun, they can burn a
larger proportion of their hydrogen before leaving the main sequence. As a result, red dwarfs have estimated lifespans longer than the estimated age of the universe

Emphasis mine.
