The László Papp Budapest Sports Arena, also known as Budapest Sports Arena or locally just Arena, is a multi-purpose indoor arena in Budapest, Hungary. It is the second biggest sports complex in the country after MVM Dome, which is also in the capital, and it is named after Hungarian boxer László Papp. The venue can hold up to 12,500 people in its largest concert configuration, up to 11,390 for boxing and 9,479 for ice hockey. It was built as a replacement for the Budapest Sports Hall which stood in the same place and was destroyed in a fire in December 1999. A long-distance bus station is situated under the building.

László Papp was a Hungarian professional boxer from Budapest. He was left-handed and won gold medals in the 1948 Summer Olympics in London, the 1952 Summer Olympics in Helsinki, and the 1956 Summer Olympics held in Melbourne, Australia. In his final Olympic competition he became the first boxer in Olympic history to win three successive gold medals. He won 12 of his 13 Olympic fights without losing a round, dropping only one, in his last Olympic final, to American boxer José Torres. There was not another triple gold medalist for 20 years, when Cuba's Teófilo Stevenson won three, followed by another Cuban Félix Savón as the third of the three men to accomplish the feat.
