María Dolores González Katarain (14 May 1954 – 10 September 1986), also known as Yoyes, was an iconic woman leader of Basque separatist group ETA (Euskadi Ta Askatasuna), who became a symbol because of the tragic circumstances of her life.
Yoyes was the first woman to enter the senior ETA leadership, but she decided to leave the organisation to start a new life.
Her former comrades regarded her as a traitor and she was killed by ETA in 1986 in her home town of Ordizia, during a local festival, in front of her three-year-old son.
The killing led to unprecedented criticism of ETA in the Basque Country.
