The boxing tournaments at the 2020 Summer Olympics in Tokyo took place from 24 July to 8 August 2021 at the Ryōgoku Kokugikan. Thirteen events were staged, the same number as in London in 2012 and Rio de Janeiro in 2016. However, for the first time since the London Games, the programme has been updated, with the number of men's events reduced by two and the number of women's events increased by the same number.

Ryōgoku Kokugikan , also known as Ryōgoku Sumo Hall or Kokugikan Arena, is the name bestowed to two different indoor sporting arenas located in Tokyo. The first Ryōgoku Kokugikan opened its doors in 1909 and was located on the premises of the Ekōin temple in Ryōgoku, Tokyo. Although no sumo bouts were held after 1945, following the capitulation of Japan and the requisition of the building by the occupying forces, the building itself remained active until 1983, being notably used by the Nihon University. The second Ryōgoku Kokugikan is currently located in the Yokoami neighborhood of Sumida next to the Edo-Tokyo Museum. It opened in 1985, following the closure of the Kuramae Kokugikan, and is still in use today.
