Orendain is a town in the province of Gipuzkoa, in the autonomous community of the Basque Country in northern Spain. It is one of the smaller municipalities within Gipuzkoa, a province that forms part of the Basque Country region along Spain's northern coast.
The town sits within the traditional Basque territory of Gipuzkoa, an area characterised by its hilly terrain and close-knit network of small towns and villages. Like other settlements in the province, Orendain is part of a region with a distinct Basque cultural and linguistic identity.
Orendain is a minor municipality rather than a major urban centre, and it is not to be confused with other places bearing similar names. Its administrative framework is that of a Spanish municipality within the Basque autonomous community.
