El Diario Vasco Newspaper Spain is a Spanish morning daily newspaper based in San Sebastián, Basque Country. It was founded in 1934 by the Sociedad Vascongada de Publicaciones, led by conservative writers such as Juan Ignacio Luca de Tena or Ramiro de Maeztu.

Following the outbreak of the Spanish Civil War in 1936, El Diario Vasco supported the Nationalist faction and was closured by the Republican government for two months until San Sebastián was conquered by the Nationalists. In 1945 it was bought by the Falange-controlled holders of El Correo Español, which then changed its name from El Publo Vasco SA to Bilbao Editorial SA.

El Diario Vasco is currently owned by Grupo Vocento and 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 terrorists.
