Een A-type hoofdreeks ster (A V) is een hoofdreeks-ster die brandt op waterstof-fusie. Dit type ster heeft een spectraal-classificatie A en een lichtkrachtklasse V. Deze sterren hebben 1,6 tot 2,4 keer de massa van de Zon en een oppervlaktetemperatuur tussen 7100 en 9700 K. Deze temperatuur geeft de ster een witte kleur. Hierdoor wordt de ster soms ook een witte-hoofdreeks-ster genoemd.
