Mintaka, ook bekend as Delta Orionis en 34 Orionis, is ’n veelvoudige ster sowat 1 200 ligjare van die Aarde af in die sterrebeeld Jagter (Orion). Saam met Alnitak en Alnilam vorm dit die Jagter se Belt. Wanneer die Jagter naby die meridiaan is, ’n lyn wat van hemelpool tot hemelpool strek, is Mintaka die heel regterkantse ster van die Belt vir ’n waarnemer in die Noordelike Halfrond wat suid kyk.
