For the third straight Worlds, Mexico won gold, and this year it was Javier Mar and Rodrigo Montoya[1] winning for their first time and the seventh overall for Mexico.

It was Montoya's second world title, as he won men's singles in 2018.

He joins American Todd O'Neill and Mexican Álvaro Beltrán as the only men to win both singles and doubles at the World Championships.

Mar and Montoya beat Bolivians Roland Keller and Conrrado Moscoso in the final, which was the first time Bolivia had reached the finals.

The 2021 World Championships used a two-stage format with an initial group stage that was a round robin with the results used to seed players for a medal round.
