Spain was represented at the Eurovision Song Contest 1998 with the song "Spanish; Castilian: ¿Qué voy a hacer sin ti?|i=no", composed by Adolfo Estébanez, with lyrics by Mikel Herzog, and performed by Herzog himself. The Spanish participating broadcaster, Spanish; Castilian: [[Televisión Española]]|i=no (TVE), selected internally both the song and the performer.[1]
In order to select its entry for the 1998 contest, Spanish; Castilian: [[Televisión Española]]|i=no (TVE) held an internal selection. Ultimately, the song "Spanish; Castilian: ¿Qué voy a hacer sin ti?|i=no" performed by Mikel Herzog was selected. It was announced as the Spanish entry on 5 March 1998.[1]
Heading into the final of the contest, BBC reported that bookmakers ranked the entry joint 20th out of the 25 entries.[2] Herzog performed fourth in the running order, following France and preceding Switzerland. He received 21 points for his performance, coming 16th.[3] Spain originally gave its 12 points to Israel and 10 to Norway. After the broadcast it was announced that the Spanish broadcaster had wrongly tallied the votes and Germany should have received 12 points instead of zero, as shown during the broadcast. The mistake was corrected and thus Germany received the 12 points. Israel and Norway both received 2 points less than originally and Croatia, Malta, Portugal, the United Kingdom, the Netherlands, Belgium, Estonia and Turkey all received one point less than indicated during the broadcast.
