Isaías Carrasco (1964 – March 7, 2008) was a Basque politician, affiliated with the PSE. He was shot dead when he left his house in Tolosa de Mondragón on March 7, 2008, two days ahead of general elections in Spain, in what is believed to be an attack by ETA.

The electoral campaign was suspended on the part of the politicians, in response to the murder of councilman Carrasco. He was shot in the presence of his wife and daughter. According to sources of the investigation, a disguised gunman approached him from behind and shot him three times; once in the nape of the neck and twice in the chest. The emergency services transferred him to the hospital in very serious condition. Shortly after the 14:00 local time (13:00 UTC) the Basque Department of Interior confirmed his death.

According to some eyewitnesses, the killer was tall, with a dark complexion in a leather jacket, and fled in a gray vehicle with an accomplice. According to police the main suspect of killing Carrasco would be the current chief of ETA Jurdan Martitegi as the description with Martitegi's two meters height.
