The 2021 Summer Deaflympics, officially known as the 24th Summer Deaflympics or XXIV Summer Deaflympics, and commonly known as Caxias Do Sul 2021, was an international multi-sport event held from 1 to 15 May 2022 in Brazil. The main host city was Caxias do Sul, Brazil, originally scheduled for December 2021 but postponed until May 2022 due to the COVID-19 pandemic. In addition to Caxias, there were events scheduled for the neighboring cities of Farroupilha and Flores da Cunha. In April 2022, CISS has announced that due to the Russian invasion of Ukraine, Russian and Belarusian athletes were barred from competing in Caxias do Sul, and in the same press release it was also announced that the bowling tournament was scheduled to be held in Kuala Lumpur, Malaysia, during October 2022.
