The Madrid electoral board met overnight and, with no other candidate putting themselves forward for election ahead of the deadline, it was confirmed that the long-serving Perez would continue in the post.
The 70-year-old is now set to remain as president of the European and Spanish champions until 2021, taking his overall stay in the position to 18 years.
A club statement read: "In Madrid, on 19 June 2017, at 00:01 hours, the electoral board of Real Madrid met at their headquarters in order to deal with and decide the issues listed below.
"As no other candidature was put forward to the board and by virtue of article 40, paragraph E, item 2 of the current articles of association within the club, is it proclaimed that Mr Florentino Perez Rodriguez is president of Real Madrid."
Madrid also confirmed the make-up of the club's board of directors.
