'''Theta Scorpii''' ('''θ Scorpii''', abbreviated '''Theta Sco''', '''θ Sco''') is a [[binary star]] in the [[Southern celestial hemisphere|southern]] [[zodiac]] [[constellation]] of [[Scorpius]]. The [[apparent visual magnitude]] of this [[star]] is +1.87,<ref name=clpl4_99/> making it readily visible to the naked eye and one of the [[List of brightest stars|brightest stars]] in the [[night sky]]. It is sufficiently near that the distance can be measured directly using the [[stellar parallax|parallax]] technique and such measurements obtained during the ''[[Hipparcos]]'' mission yield an estimate of approximately {{Convert|101|pc|ly|abbr=off|lk=on|order=flip|sigfig=3}} from the [[Sun]].

The two components are designated '''θ Scorpii A''' (officially named '''Sargas''' {{IPAc-en|'|s|ɑr|g|æ|s}}, the traditional name for the system)<ref name=Kunitzsch/><ref name="IAU-LSN"/> and '''B'''.
