'''Delta Scorpii''' ([[Latinisation of names|Latinised]] from '''δ Scorpii''', abbreviated '''Delta Sco''', '''δ Sco''') is a [[binary star]] (the presence of a third star in the system is being debated<ref name=miro/>) in the [[constellation]] of [[Scorpius]]. The primary star is named '''Dschubba''' {{IPAc-en|'|dZ|V|b|@}}.<!--this appears to be one of those annoying cases where K&S don't bother to give the English pronunciation because it's the same as their ad hoc pseudo-Arabic pronunciation.--><ref name=Kunitzsch/><ref name="IAU-CSN"/>
