Hauptreihensterne der Spektralklasse O (oder auch O-Sterne der Leuchtkraftklasse V) sind die größten, heißesten und auch massereichsten (15 bis 90-fache Sonnenmasse) Sterne der Hauptreihe und befinden sich links oben im Hertzsprung-Russell-Diagramm. Die meisten massereichen Sterne gehören in ihrer Anfangsphase dieser Sternklasse an.
