Geir is a maculine name commonly given in Norway and in Iceland. It is derived from Old Norse geirr "spear", a common name element in Germanic names in general, from Proto-Germanic *gaizaz (whence also Old High German gêr, Old English gâr, Gothic gaisu).
The popularity of the given name peaked in Norway during the 1950s to 1980s, with above 2% of newly born boys named Geir during the late 1960s to 1970s. As of 2014, the National statistics office of Norway recorded 22,380 men with the given name, or 0.9% of total male population. The Old Norse spelling Geirr is also rarely given (89 individuals in Norway as of 2014). Geir is also rarely given in Sweden and Denmark.
While Geir was practically unused as a given name prior to the 1930s (and since the 2000s), -geir is the second element in a number of given names inherited from Old Norse, the most popularly given being Asgeir and Torgeir. These are a remnant of a much larger group of names including the geirr element in Old Norse.
