En astronomie, une étoile orange de la séquence principale, appelée communément naine orange, est une étoile de type K V (lire « K cinq »), c'est-à-dire une étoile appartenant à la séquence principale (classe de luminosité V) de type spectral K (étoile orange). Elles se situent entre les naines jaunes (analogues au Soleil) et les naines rouges. Elles ont des masses de l'ordre de 0,5 à 0,8 fois celle du Soleil et des températures de surface comprises entre 3900 et 5 200 K.
