Palmistry is the practice of fortune-telling through the study of the palm. Also known as palm reading, chiromancy, chirology or cheirology, the practice is found all over the world, with numerous cultural variations. Those who practice palmistry are generally called palmists, hand readers, hand analysts, or chirologists.

There are many—and often conflicting—interpretations of various lines and palmar features across various teachings of palmistry. Palmistry is practiced by the Hindus and is still practiced in South India widely as an hereditary job by several castes such as Kuravan from Kerala, and is also indirectly referenced in the Book of Job. The practice is widely viewed as a pseudoscience due to various contradictions between different interpretations and the lack of evidence for palmistry's predictions.
