'''Alpha Centauri''' (α Cen / α Centauri) adalah bintang yang paling cerah dalam [[konstelasi]] [[Centaurus]]. Walaupun tampak seperti satu titik dilihat dengan mata telanjang, bintang ini sebenarnya adalah sistem tiga bintang. Alpha Centauri terkenal di belahan bumi selatan sebagai bintang paling luar dalam [[Crux|Southern Cross]], namun letaknya terlalu jauh di selatan untuk dapat terlihat di belahan bumi utara. Kedua bintang terbesar dalam sistem ini terlalu dekat untuk dibedakan oleh mata telanjang sehingga terlihat seperti satu sumber cahaya dengan magnitude −0,27.▼
