Main article: 2018 Miami Open

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Federer and Rafael Nadal (despite having withdrawn from the event) were in contention for the ATP No. 1 singles ranking. 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 Big Four won a match at a Masters 1000 tournament.^[1][2][3][4]
