'''Centaurus A''' atau '''NGC 5128''' adalah sebuah galaksi yang menonjol di [[konstelasi]] [[Centaurus]]. Galaksi ini ditemukan pada 1826 oleh [[Scotland|Scottish]] astronomer [[James Dunlop]] dari rumahnya di Parramatta, di New South Wales, Australia. Terjadi perdebatan dalam literatur mengenai sifat dasar galaksi seperti [[tipe Hubble]] ([[lenticular galaxy]] atau [[Galaksi Elip raksasa]])<ref name=harris10b/> dan berjarak (10–16 juta [[tahun cahaya]]).<ref name="tonryetal2001"/><ref name=ned-dist/><ref name=ferrarese07/><ref name=majaess10/><ref name=harris10/> NGC 5128 adalah salah satu [[galaksi radio]] paling dekat dengan Bumi, jadi [[inti galaksi aktif]]nya telah dipelajari secara ekstensif oleh para astronom profesional.<ref name="israel1998">{{cite journal
