Une étoile bleue de la séquence principale est une étoile de type spectral OV. Les étoiles de ce type ont une masse comprise entre 15 et 90 fois celle du Soleil et une température de surface comprise entre 30 000 et 52 000 kelvins. Elles sont entre 30 000 et 1 000 000 fois plus lumineuse que le Soleil. Ce type d'étoile est rare : on estime en effet qu'il n'y a pas plus de 20 000 dans l'ensemble de la Voie lactée. Des exemples sont Sigma Orionis et 10 Lacertae,.
