El Diario Vasco (English: The Basque Daily) is a Spanish morning daily newspaper based in San Sebastián, Basque Country.

[1] Following the outbreak of the Spanish Civil War in 1936, El Diario Vasco supported the Nationalist faction and was closed by the Republican government for two months until San Sebastián was conquered by the Nationalists.

In 1945 the paper was bought by the Falange-controlled holders of El Correo Español, which then changed its name from El Pueblo Vasco SA to Bilbao Editorial SA.

[4] The paper publishes ten editions through Guipúzcoa and one for the rest of Spain.

In May 2001 its chief financial officer Santiago Oleaga was killed by two ETA militants.
