Manigiramam, or manigramam, typically refers to a medieval merchant guild organized by itinerant ethnic Indian traders, primarily active in southern India. Along with the ainurruvar (the Ayyavole Five Hundred) and the anjuvannam (the anjuman), the manigiramam played a significant role in the commercial activities of the region. Unlike the anjuvannam, which was confined to the port-towns of southern India, the manigramam operated in both port towns and hinter-land trade centers.
A body of merchants known as "the Vaniggrama" or "Vaniyagrama" is attested in northern India as early as the first century BCE. They are mentioned in a Karle inscription (first century BCE), a charter of king Vishnusena from Kathiawad (6th century CE), and in a Sanjeli charter of king Toramana (6th century CE).
