The Department of Corrections (Thai: กรมราชทัณฑ์ กระทรวงยุติธรรม) is an agency of the Thai Ministry of Justice. Its mission is to keep prisoners in custody and rehabilitate them. Its headquarters is in Suanyai Sub-district, Mueang Nonthaburi District, Nonthaburi Province.
Bang Kwang houses Thailand's death row for men and execution chamber. The Klong Prem (Lard Yao) section for women houses female death row inmates.
The Department of Corrections is moving towards separating lesbian, gay, bisexual, and transgender (LGBT) prisoners from other prisoners to ensure their safety and security. Min Buri Prison will be used as a prison for LGBT prisoners under a pilot scheme. There are 4,448 prisoners self-identified as LGBT: 2,258 females, 2,156 males, and 34 transgender individuals. LGBT inmates account for about one percent of Thailand's total of 300,000 prisoners.
