The drivers took to the track at the Miami International Autodrome for the first time on a hot day in Florida.
Leclerc used the Soft rubber to clock a time of 1:21.098, but the Mercedes of George Russell (also on Softs) was just 0.071 seconds behind.
Russell placed second, followed by the two Red Bull cars of Max Verstappen (+0.179s) and Sergio Perez (+0.203s).
Alex Albon impressed the crowds in Miami Gardens with the stand-out lap of the session, placing seventh with a lap almost four seconds faster than his teammate, Nicholas Latifi.
