Arngrímr Brandsson (died 13 October 1361) was an Icelandic cleric and writer.
Arngrímr‘s early life and career has long been the subject of debate; the evidence for it is sometimes contradictory.
[1] In this account, Arngrímr was consecrated as a secular priest, held the benefice of Oddi, and served Bishop Jón Halldórsson of Skálholt.
Arngrímr supported the otherwise unpopular Bishop Ormr Ásláksson, during whose episcopate Arngrímr rose to the position of officialis of Iceland's northern diocese of Hólar, which he held from 1347 to 1351 and again from 1354 to 1357.
Arngrímr is now most noted for making the latest and longest version of Guðmundar saga biskups, known as version D, probably at Ormr Ásláksson‘s request, and in conjunction with Bishop Guðmundur Arason's exhumation in 1344.
