Mueang Ratchaburi is the capital district (amphoe mueang) of Ratchaburi Province, western Thailand. Neighbouring districts are (from the north clockwise) Photharam and Damnoen Saduak of Ratchaburi Province, Bang Khonthi of Samut Songkhram Province, Wat Phleng, Pak Tho and Chom Bueng of Ratchaburi. The main river of the district is the Mae Klong.
The history of the area can be dated back to the Dvaravati town Khu Bua, just a few kilometres south of the modern town of Ratchaburi. After being deserted for about 300 years, the town was reestablished near Wat Mahathat by King U-Thong of the Ayutthaya Kingdom. In 1817 the town centre was moved to the other bank of the Mae Klong River. The district was one of the five original districts of Monthon Ratchaburi that were established in 1895 with Phraya Surinthararuchai (Thet Bunnag) as the first superintendent commissioner. At first the provincial administration was in Photharam District, but was moved to tambon Na Mueang in 1898.
The district is divided into 22 sub-districts (tambon), which are further subdivided into 187 villages (muban). The town (thesaban mueang) Ratchaburi covers the complete tambon Na Mueang. The township (thesaban tambon) Khao Ngu covers parts of tambon Chedi Hak and Ko Phlapphla. Lak Mueang covers the Khok Mo. Phong Sawai, and Huai Chinsi and all of Ang Thong. There are a further 18 tambon administrative organizations (TAO).
