The Paleolithic or Palaeolithic (pronunciation: /ˌpeɪliəˈlɪθɪk, ˌpæ-, -lioʊ-/) Age, Era, or Period is a prehistoric period of human history distinguished by the development of the most primitive stone tools discovered (Grahame Clark's Modes I and II), and covers roughly 95% of human technological prehistory. It extends from the earliest known use of stone tools, probably by Homo habilis initially, 2.6 million years ago, to the end of the around 10,000 BP.

The Paleolithic era is followed by the Mesolithic. The date of the Paleolithic–Mesolithic boundary may vary by locality as much as several thousand years.

During the Paleolithic period, humans grouped together in small societies such as bands, and subsisted by gathering plants and fishing, hunting or scavenging wild animals. The Paleolithic is characterized by the use of knapped stone tools, although at the time humans also used wood and bone tools. Other organic commodities were adapted for use as tools, including leather and vegetable fibers; however, due to their nature, these have not been preserved to any great degree. Surviving artifacts of the Paleolithic era are known as paleoliths.
