The 2019 Southeast Asian Games, officially known as the 30th Southeast Asian Games, or 2019 SEA Games and commonly known as Philippines 2019, was the 30th edition of the Southeast Asian Games, a biennial regional multi-sport event which was held in the Philippines from 30 November to 11 December 2019. However, due to a narrow calendar, some sports started before the opening ceremony as early as 24 November.
This edition was marked by the first major decentralisation in the history of the Games, with competition venues spread in 23 cities across the country and divided into four clusters; all were located on the island of Luzon (Metro Manila, Clark, Subic/Olongapo, and a fourth cluster consisting of standalone venues in Batangas, Cavite, Laguna, and La Union). This was the Philippines' fourth time to host the games, and its first since 2005. Previously, it had also hosted the 1981 and 1991 editions of the games. This edition was most notable for being the first edition to include esports, obstacle course race, kurash, sambo, underwater hockey, breaking, surfing, modern pentathlon, jiu-jitsu, kickboxing, and skateboarding; as well as having the highest number of sports in the history of the games, at a total of 56.
The hosting rights were originally awarded to Brunei in 2012, but the country pulled out days before the 2015 Southeast Asian Games due to "financial and logistical reasons."
