The men's vault event at the 2020 Summer Olympics was held on 24 July and 2 August 2021 at the Ariake Gymnastics Centre. Unlike the other apparatus events, vault requires gymnasts to perform two exercises in order for results to count towards the vault final; most of the gymnasts perform only one (if they are participating in team or individual all-around) or none (if they are participating in only other apparatus). Approximately 20 gymnasts from 15 nations (of the 98 total gymnasts) competed two vaults in the qualifying round.
