Vettius Valens (120 – c. 175) was a 2nd-century Hellenistic astrologer, a somewhat younger contemporary of Claudius Ptolemy.

Valens' major work is the Anthology (Latin: Anthologia), ten volumes in Greek written roughly within the period 150 to 175. The Anthology is the longest and most detailed treatise on astrology which has survived from that period. A working professional astrologer, Valens includes over a hundred sample charts from his case files in the Anthology.
