The d'Orsi Senior Bowl, or Senior Bowl or d'Orsi Bowl, is a biennial world championship contract bridge tournament for national teams of "Seniors", players age 60 and older.[a] It is contested every odd-number year under the auspices of the World Bridge Federation (WBF), alongside the Bermuda Bowl (Open), Venice Cup (Women) and Wuhan Cup (Mixed). Entries formally represent WBF Zones as well as nations so it is also known as the "World Zonal Senior Team Championship", one of three "World Zonal Team Championships".[1][2] It became an official world championship event in 2001 following a successful exhibition in 2000.
The d'Orsi Senior Bowl is also the trophy awarded to the winning team. It was donated at the 2009 tournament in Brazil by former WBF President Ernesto d'Orsi,[b] and the tournament was renamed at that time.[3]
The most recent event took place in 2023 in Marrakech, Morocco.[4]
