The Little Women actor, who has gained a reputation for his enviable style on the red carpet, ranked higher than stars including actor Brad Pitt, singer Troye Sivan and rapper Skepta.
The list includes 50 of the best-dressed men across the globe, as decided by British GQ.
The esteemed publication stated that Chalamet is an example of an actor who takes successful sartorial risks on the red carpet.
"Plenty of actors decide to take risks on the red carpet, and for that we applaud them, but so often it backfires," the magazine wrote.
"Not so with Timothée Chalamet, who wears the trickiest of designer ensembles but manages to look as cool and comfortable as if he were wearing regular black tie."
