Mueang Nakhon Nayok (, ) is the capital district (amphoe mueang) of Nakhon Nayok province, central Thailand.

History Mueang Nakhon Nayok is an ancient city. In the Ayutthaya kingdom it was the eastern frontier city. The historians found the old city wall on three sides, the southern side was protected by the Nakhon Nayok River as a natural city wall.

The moated site of Mueang Boran Dong Lakhon, in the subdistrict of the same name, lies on a former shoreline of the Gulf of Thailand and has been occupied since at least the sixth century. In a survey of fifteen moated sites of eastern Thailand by Patcharaporn Ngernkerd and colleagues it is a village, the smallest of three ranks, measuring 0.38 km² within its moat. A group of Buddhist buildings stands at its outer moat, following the pattern of Dvaravati towns of the central plain, and a Pali inscription carrying the ye dhammā formula has been recovered there.

The district was called Wang Krachom as the office was in Tambon Wang Krachom, on the left bank of the Nakhon Nayok River. In 1896 the government moved the district office to the right bank of the river. The district office was moved to the old provincial court building in 1931. A new district office was opened on 18 January 1953.

The district name was changed to Mueang Nakhon Nayok on 1 January 1939, to correspond with the name of the province. On 1 January 1943, the government downgraded Nakhon Nayok Province and combined it with Prachinburi province, except Ban Na which became part of Saraburi province. During that time the district was called Nakhon Nayok District. On 9 May 1946, the government re-established Nakhon Nayok Province, thus the district was renamed Mueang Nakhon Nayok.
