Beta Centauri (β Centauri, β Cen) vel Hadar, interdum et Agena, est stella constellationis Centauri. A Sole circa 392 annos luce mensos distat.

Stella trinaria est. Stella systematis principalis gigas caeruleus et albus est; anno 1935 Ioannes Voûte^(nl) stellam alteram aperuit, quae a principali 1,3 secunda anguli distat. Periodis sidericus longior est, nam tempore observationis stellae vix moventur. Stella principalis binaria spectroscopica est; periodum sidericum 352 dies habet.
