Mueang Nakhon Ratchasima (Thai: เมืองนครราชสีมา, in Thai pronounced as /mɯ̄aŋ ná(ʔ).kʰɔ̄ːn râːt.tɕʰā.sǐː.māː/; เมืองนครราชสีมา, in Lao pronounced as /mɯ̄aŋ nà(ʔ).kʰɔ᷇ːn lâːt.sā.sǐː.ma᷇ː/) is one of 32 districts of Nakhon Ratchasima province, northeastern Thailand.
Nakhon Ratchasima was built in the reign of King Narai the Great of Ayutthaya kingdom. The king merged two cities, Mueang Sema and Mueang Khorakha Pura (Khorat), and moved to the present area. He named the new city "Nakhon Ratchasima".
"Khorat", as it is commonly known, is on the Khorat plateau, the lower part of northeastern plateau of Thailand. The city itself serves as the gateway to the northeastern region. From Bangkok, it is 259 km by road. It has an area of 468704rai with a population of 433,838 inhabitants (2008).
