Þórbjǫrn Hornklofi (Modern Norwegian: Torbjørn Hornklove) was a 9th-century Norwegian skald and one of the court poet of King Harald Fairhair. His poetry provides the only contemporary sources of information regarding King Harald.
A portion of two skaldic poems by him which are preserved are Hrafnsmál and Glymdrápa. The first poem, which utilizes verse form málaháttr, describes life at Harald's court, mentions that he took a Danish wife, and that he won a victory at the Battle of Hafrsfjord. The second is a drápa which relates a series of battles Harald won during the consolidation of his rule of Norway.
