The 1999 SEA Games, officially known as the 20th SEA Games and commonly known as Brunei Darussalam 1999, was a Southeast Asian multi-sport event held in Bandar Seri Begawan, Brunei. This was the first time Brunei hosted the Southeast Asian Games and also in Borneo island. These were the last to have ever staged during the 20th century, and this was the only occasion, to date, that Brunei had held the SEA Games.
