John Isner defeated Alexander Zverev in the final, 6-7^(4-7), 6-4, 6-4 to win the men's singles tennis title at the 2018 Miami Open. It was his maiden Masters 1000 title. Isner became the first new Miami Open champion in nine years.

Roger Federer was the defending champion, but lost in the second round to Thanasi Kokkinakis.

Federer and Rafael Nadal (despite having withdrawn from the event) were in contention for the ATP No. 1 singles ranking at the start of the tournament. Nadal regained the top ranking as a result of Federer's second round loss.

With Novak Djokovic and Federer losing their opening matches and Andy Murray and Nadal missing the tournament due to injuries, this was the first time since the 2004 Paris Masters that none of the members of the Big Four won a match at a Masters 1000 tournament.^[1][2][3][4]
