Named by the French astronomer Nicolas Louis de Lacaille in 1763. From later Latin rēticulum (“reticle”). The meaning is often wrongly interpreted as "net", which is an older meaning of the Latin root word. Doublet of reticle, reticule, and reticulum.

Reticulum is a small, faint constellation in the southern sky. Its name is Latin for a small net, or reticle—a net of crosshairs at the focus of a telescope eyepiece that is used to measure star positions. The constellation is best viewed between October and December, but cannot be seen from middle to northern latitudes.
