The [[Bayer designation|designation]] of Arcturus as ''α Boötis'' ([[Latinisation of names|Latinised]] to ''Alpha Boötis'') was made by [[Johann Bayer]] in 1603. In 2016, the [[International Astronomical Union]] organized a [[IAU Working Group on Star Names|Working Group on Star Names]] (WGSN) to catalog and standardize proper names for stars. The WGSN's first bulletin of July 2016 included a table of the first two batches of names approved by the WGSN, which included ''Arcturus'' for α Boötis.<ref name="WGSN1" /><ref name="IAU-CSN" />
