Euskaltel, S.A. is a Spanish telecommunications company based in Derio, Basque Country.

Euskatel operates a fibre optics network within the region, laid in collaboration with the Basque gas company.

Although Euskaltel has its own cable network, it doesn't have a licence to use mobile phone aerials.

Euskaltel was the joint lead sponsor of the Basque Country's major professional cycling team, Euskaltel–Euskadi, along with the regional government.

The team, once one of eighteen elite teams making up the UCI ProTour, was a regular participant in the annual Tour de France and Vuelta a España, and has helped to launch the careers of many top Basque professional cyclists such as Iban Mayo and Haimar Zubeldia.
