Chaeng Watthana Government Complex (Thai: ศูนย์ราชการแจ้งวัฒนะ), or formally, the Government Complex Commemorating His Majesty the King's 80th Birthday Anniversary, 5 December, BE 2550 (2007) (Thai: ศูนย์ราชการเฉลิมพระเกียรติ 80 พรรษา 5 ธันวาคม 2550), is a complex of Thai Government buildings on Chaeng Watthana Road, Thung Song Hong Subdistrict, Lak Si District, Bangkok. The complex was built in commemoration of King Bhumibol Adulyadej's 80th birthday. The complex construction project started in 2005 under Thaksin Shinawatra's regime and was completed in 2008.[1] Its opening ceremony was held on 17 February 2010 by Crown Prince Vajiralongkorn and Prince Dipangkorn Rasmijoti.[2] The project cost 20,000 million baht.[1]
The 349 rai (55.8 ha; 138 acres)[1] of land on which the complex sits belongs to the Treasury Department, Ministry of Finance.[3] The complex is administered by Dhanarak Asset Development (ธนารักษ์พัฒนาสินทรัพย์) or DAD, a state enterprise attached to the Treasury Department.[4]

The complex is divided into three zones: Zone A (100 rai) and Zone B (197 rai) are for government buildings, and Zone C (152 rai) supports the growth of the complex itself.[1] The governmental buildings in the complex are divided into two groups:
Building A (อาคารเอ), or formally, the Ratchaburidirekrit Building (อาคารราชบุรีดิเรกฤทธิ์; named for Prince Raphi Phatthanasak, Prince of Ratchaburi (1874–1920), whom some consider to be the "father of Thai law"), is in Zone A and includes the justice-related agencies:
