Uma estrela anã-vermelha, de acordo com o Diagrama de Hertzsprung-Russell é uma estrela pequena e relativamente fria da sequência principal. O seu tipo espectral pode ser K ou M. As anãs-vermelhas constituem a vasta maioria das estrelas e sua massa é menor que a metade da massa do Sol (entre 0,075 e 0,5 massas solares). A temperatura de superfície é menor que 3500 K.
