Chatuchak (, ) is one of the 50 districts (khet) of Bangkok, Thailand. The district is bounded by seven other districts (from the north clockwise): Lak Si, Bang Khen, Lat Phrao, Huai Khwang, Din Daeng, Phaya Thai, and Bang Sue. History Chatuchak was originally part of Bang Khen district. It became a separate district in 1989. The name of the district came from its two major landmarks, Chatuchak Park and Chatuchak Weekend Market. Government and infrastructure The district is divided into five sub-districts (khwaeng). The Department of National Parks, Wildlife and Plant Conservation, Royal Forest Department and Department of Fisheries with Criminal Court of Thailand as well as Department of Land Transport have their headquarters in the district. Central Juvenile and Family Court is located on Kamphaeng Phet Road near Bang Sue Grand Station. Klong Prem Central Prison, also known as "Lat Yao Prison", is in the district. Markets The best-known site in the district is the Chatuchak Weekend Market, the largest market in Thailand. Northwest of the weekend market is another market, Chatuchak Plaza, which sells clothes and many other products. Across Kamphang Phet Road is Or Tor Kor Market (ตลาด อ.ต.ก.) belonging to The Marketing Organization for Farmers (องค์การตลาดเพื่อการเกษตร), offering fresh agricultural products and food. Just north of the market along Kamphang Phet Road is an area selling plants and garden products. Parks Adjoining the Chatuchak Weekend Market to the north is the Chatuchak Park complex, covering 1.13 km2 of a former State Railway of Thailand golf course consisting of Chatuchak Park (สวนจตุจักร), Queen Sirikit Park (สวนสมเด็จพระนางเจ้าสิริกิติ์ฯ), and Wachirabenchathat Park (สวนวชิรเบญจทัศ). Chatuchak Park (0.304 km2) is the first park in the complex. It opened in December 1980 and is on Phahonyothin Road next to the Mo Chit BTS Station. It is the most accessible park of the three. Also included in this park is the Train Museum. Queen Sirikit Park (0.224 km2) is a botanical garden built to honor the queen's 60th birthday in 1992. It was formally opened in December 1996. Plants collected in the garden include hibiscus, plumeria, and palms. Within the park compound is the Children's Museum. The park is behind the Chatuchak Weekend Market parking lot. The Wachirabenchathat Park (0.600 km2) is the biggest and newest park of the complex. It was called State Railway Public Park (สวนรถไฟ, Suan Rot Fai) but was renamed in July 2002 in honor of Prince Maha Vajiralongkorn's 50th
