Hesper is a term with multilingual and historical usage rooted in Greek and Latin, commonly associated with the notions of the evening or the western horizon. In English, it may evoke the sense of the western sky or the time of dusk, and it is related to other classical forms such as Hesperos and Hesperia.

In classical literature, Hesper is used as a poetic reference to the evening or the western sky. The term is etymologically linked to the Hesperides, the nymphs said to guard a garden at the western edge of the world. Over time, Hesper and its derivatives have appeared in poetry and prose to invoke twilight, the west, or distant western lands.

In astronomy and planetary science, related forms carry specific meanings. Hesperus is the traditional personification and name for the Evening Star, which is Venus. In Martian geology, the term Hesperian denotes a major epoch in the planet’s geological history; the name reflects classical associations with western or western-oriented naming conventions used by scientists when classifying Martian rocks and surfaces.

In modern usage, Hesper appears mainly as a given name or surname and as a literary or academic allusion. It is less common than related forms such as Hesperus or Hesperia, but it remains encountered in historical texts, poetry, and some fictional works.
