Topo is the name of two frequent suburban rail services operated by Euskotren in the city of San Sebastián and the surrounding Donostialdea area, in the Basque Country, Spain, up to Hendaye just over the French border. The infrastructure is gradually being upgraded to rapid transit standards, in order to create the San Sebastián Metro (Spanish: Metro de San Sebastián, Basque: Donostiako metroa). The line is commonly known as Topo (Spanish for 'mole'), due to the large number of tunnels present. As of 2021, the San Sebastián suburban rail services are branded as part of the Euskotren Trena network, with no separate identity.
