Eilert is a male given name originating as a Low German and Scandinavian form of the Old German name Egilhard. Egilhard is composed of the elements agil (meaning "edge, blade") and hart (meaning "hard, firm, brave, hardy"). The variant Eilhart was borne by a medieval German poet who authored an early version of the tale of Tristan and Iseult, cementing the name's association with martial valor and literary romance. Etymology and related forms The name Eilert belongs to a broader family of Germanic names formed from similar roots, including Eckhard, Eckhart, and Ekkehard, all of which evoke strength and sharpness (through the element ag-). The variant Eike is another German shortening, while the Scandinavian adoption of Eilert reflects the historical Nether-Saxon influence of the Hanseatic League in Norway and Sweden. Notable bearers Eilert has been borne by a diverse array of individuals: Eilert Sundt (1817–1875), Norwegian sociologist known for pioneering studies on mortality and poverty. Eilert Ekwall (1877–1964), Swedish philologist and professor of English who compiled authoritative place-name studies.

Eilert Dahl (1919–2004), Norwegian Nordic skier and Olympian. Eilert Pilarm (born 1953), Swedish Elvis Presley impersonator.
