Coenagrion hastulatum, the northern damselfly or spearhead bluet, is a damselfly in the family Coenagrionidae.

The species is widespread and common in northern Eurasia but is restricted to elevated or bog-like sites towards the west and south.[1] In Britain, it is confined to a few small lochans in Scotland.[2]

C. hastulatum is 31–33 millimetres (1.2–1.3 in) long.[3]

The specific part of the scientific name, hastulatum, from the Latin hastula (small spear) is because of the distinctive markings on the second segment of the abdomen that resembles a spear.[4]
