''γ Crucis'' (Latinised to ''Gamma Crucis'') is the star's [[Bayer designation]]. Gacrux is currently at roughly 60° south [[declination]]. It was known and visible to the [[Ancient Greece|ancient Greeks]] and [[Ancient Rome|Romans]] as it was visible north of 40° [[latitude]] because of the [[precession of equinoxes]]. Oddly, it lacked a traditional name. The astronomer [[Ptolemy]] counted it as part of the constellation of [[Centaurus]].<ref>Richard Hinckley Allen, "Star Names: Their Lore and Meaning", Dover Press, 1963.</ref> The name ''Gacrux'' was coined by astronomer Elijah Hinsdale Burritt (1794-1838) as a contraction of the Bayer designation.<ref>{{cite web|title=Gacrux/Gamma Crucis 2?|url=http://www.solstation.com/stars2/gacrux2.htm|publisher=SolStation.com|access-date=2011-11-03 |archive-url=https://web.archive.org/web/20230407220320/http://www.solstation.com/stars2/gacrux2.htm |archive-date=7 April 2023 |url-status=dead}}</ref><ref>{{cite web|last=Lesikar|first=Arnold V.|title=Gacrux|url=http://domeofthesky.com/clicks/gacrux.html|publisher=Dome Of The Sky|access-date=2011-11-03|url-status=dead|archive-url=https://web.archive.org/web/20110928143206/http://domeofthesky.com/clicks/gacrux.html|archive-date=2011-09-28}}</ref> In 2016, the [[International Astronomical Union]] organized a [[IAU Working Group on Star Names|Working Group on Star Names]] (WGSN)<ref name="WGSN">{{cite web | url=https://www.iau.org/science/scientific_bodies/working_groups/280/ | title=IAU Working Group on Star Names (WGSN)|access-date=22 May 2016}}</ref> to catalog and standardize proper names for stars.
