Palmistry, or chiromancy is the claim of characterization and foretelling the future through the study of the palm, also known as palm reading or chirology. The practice is found all over the world, with numerous cultural variations. Those who practice chiromancy are generally called palmists, palm readers, hand readers, hand analysts, or chirologists.

There are many (often conflicting) interpretations of various lines and palmar features across various schools of palmistry. These contradictions between different interpretations, as well as the lack of empirical support for palmistry's predictions, contribute to palmistry's perception as a pseudoscience among academics.

Chiromancy consists of the practice of evaluating a person's character or future life by "reading" the palm of that person's hand. Various "lines" ("heart line", "life line", etc.) and "mounts" (or bumps) (chirognomy) purportedly suggest interpretations by their relative sizes, qualities, and intersections. In some traditions, readers also examine characteristics of the fingers, fingernails, fingerprints, and palmar skin patterns (dermatoglyphics), skin texture and color, shape of the palm, and flexibility of the hand.
