Erandio is a town and municipality located in the province of Biscay, in the autonomous community of Basque Country, northern Spain.

The Biscayans were defeated at Erandio with the loss of sixty men and the wheat transfers continued.

There is no direct public transport from Erandio to the passengers terminal, though buses can be taken in the neighbouring municipalities of Loiu and Bilbao.

There is a project for a pedestrian bridge, which will be called All Iron Zubia between Erandio and Barakaldo.

Regular fluvial transport service was interrupted in February 2024, due to economical difficulties caused by the rise of fuel prices and the competence of land public transport,[6][7] though private boats are occasionally hired for leisure travel along the estuary.
