Ferrari secured a shock front row lockout with Leclerc and Carlos Sainz at the Autodromo Hermanos Rodriguez as Max Verstappen, who had topped all three practice sessions, ended the decisive Q3 session third fastest for Red Bull.
The final classification was subject to a number of post-qualifying investigations, with Verstappen and George Russell plus his Mercedes team-mate Lewis Hamilton among those summoned to face the stewards for pitlane impeding and a yellow flag infringement respectively.
