Angel Maria Villar, the president of the Royal Spanish Football Federation (RFEF), is to stand as a candidate in the UEFA presidential election.
Villar stood in for disgraced former UEFA chief Michel Platini during Euro 2016, but it was not known whether he would pursue the role full time.
However, the RFEF confirmed in a short statement on its official website that the 66-year-old intends to put his name on the ballot papers.
"The president of the Royal Spanish Football Federation, Angel Maria Villar, has made official his candidacy for the upcoming elections for the presidency of UEFA," the statement read.
Royal Dutch Football Association president Michael van Praag and Slovenian chief Aleksandar Ceferin have already stated their intention to run.
The election is scheduled to take place on September 14 in Athens.
