The men's long jump event at the 2020 Summer Olympics took place between 31 July and 2 August 2021 at the Japan National Stadium.

Cuban athletes Juan Miguel Echevarría and Maykel Massó earned silver and bronze, respectively, the nation's first medals in the event since 2008.

Maykel Massó took the lead as last jumper of the first round with an 8.21 metres, on his second attempt he seemed to tweak his left hamstring.

In the third round, Juan Miguel Echevarría put one together taking a big lead with 8.41 metres.

As the final jumper in the fourth round, Echevarría aborted his jump, coming out of the pit limping.

Leading off the fifth round, Harrison jumped 8.15 metres to move into bronze medal position.

Tentoglou answered being knocked off the podium by jumping 8.41 metres, matching Echevarría exactly.

It was time for the Cubans to answer, but Massó couldn't go, passing his final attempt, settling for bronze.

Due to the COVID-19 pandemic, the period was suspended from 6 April 2020 to 30 November 2020, with the end date extended to 29 June 2021.
