Harald "Bluetooth" Gormsson (Old Norse: Haraldr Gormsson,Danish: Harald Blåtand Gormsen, died c. 985/86) was a king of Denmark and Norway.

He was the son of King Gorm the Old and of Thyra Dannebod. His father had been the first ruler of the Danish kingdom and founder of the Jelling dynasty. Harald ruled as king of Denmark from c. 958. Harald introduced Christianity to Denmark and consolidated his rule over most of Jutland and Zealand. Harald's rule as king of Norway following the assassination of King Harald Greycloak of Norway was more tenuous, most likely lasting for no more than a few years in the 970s. Some sources say his son Sweyn Forkbeard forcibly deposed him from his Danish throne before his death.

Harald's name is written as runic haraltr : kunukʀ (ᚼᛅᚱᛅᛚᛏᚱ ᛬ ᚴᚢᚾᚢᚴᛦ) in the Jelling stone inscription. In normalized Old Norse, this would correspond to Haraldr konungr, i.e. "Harald king". The latinized name as given in the medieval Danish chronicles is Haraldus Gormonis filius. The given name Haraldr (also Haralldr) is the equivalent of Old English Hereweald, Old High German Heriwald, from hari "army" and wald- "rule". Harald's name is also inscribed on the so-called Curmsun disc, rediscovered in 2014 (but part of a Viking hoard previously discovered in 1841 in the crypt of the Groß-Weckow village church in Pomerania, close to the Viking Age stronghold of Jomsborg), as +ARALD CVRMSVN + REX AD TANER + SCON + JVMN + CIV ALDIN, i.e. "Harald Gormson, king of Danes, Scania, Jumne, Oldenburg".
