Na Thawi (th|นาทวี, pronounced as /th/; Pattani Malay: นาวี, pronounced as /th/) is a district (amphoe) in the southern part of Songkhla province, southern Thailand.
NaThawi District was originally the location of Chana District, Songkhla Province. The brief history is that Chana District was previously called Mueang Chana. The city was located in Tambon Chanong, Chana District. Later, Chana City was moved to Tambon Na Thawi, to the east of the Na Thawi District Office. At that time, Chana City was a third-class city with Khun Si Sanphakham (Mr. Son) as its governor. Later, during the reign of King Rama V, King Chulalongkorn graciously ordered the current Chana City to be moved because at that time, transportation in Tambon Na Thawi was inconvenient.
When the Local Administration Act B.E. 2475 was announced, Chana City was changed to "Chana District" and the status of Tambon Na Thawi, which was the location of Chana City, was raised to include nearby sub-districts as "Na Thawi Minor District" under Chana District and later announced as a district.
On June 1, 1947, Chang Sub-district was established, separated from Na Thawi Sub-district. Khlong Sai Sub-district was established, separated from Na Mo Si Sub-district. Tha Pradu Sub-district was established. Separated from Tambon Plak Nu, established Tambon Saton, separated from Tambon Thap Chang

May 24, 1977, transferred the area of Village No. 7 (at that time) of Tambon Prakop to be Village No. 9 of Tambon Saton
July 1, 1980, established Khlong Kwang Subdistrict, separated from Tambon Plak Nu
June 18, 1992, changed the Na Thawi Sanitary District area for the appropriateness of local administration and maintenance
