The Radhanites (also Radanites, Arabic الرذنية ar-Raðaniyya; Hebrew sing. רדהני Radhani, pl. רדהנים Radhanim) were medieval Jewish merchants. Whether the term, which is used by only a limited number of primary sources, refers to a specific guild, or a clan, or is a generic term for Jewish merchants in the trans-Eurasian trade network is unclear. Jewish merchants were involved in trade between the Christian and Islamic worlds during the early Middle Ages (approx. 500–1000). Many trade routes previously established under the Roman Empire continued to function during that period largely through their efforts. Their trade network covered much of Europe, North Africa, the Middle East, Central Asia and parts of India and China.
