Na Noi (Thai: นาน้อย, pronounced [nāː nɔ́ːj]) is a district (Amphoe) in Nan Province, northern Thailand.
Na Noi was originally named Wiang Si Sa Ket (เวียงศรีษะเกษ). In 1899 it became part of the province Nan. Though it was originally planned to merge Sisaket and Tha Pla into one district, in 1903 Tha Plan was integrated into Uttaradit Province. In 1917 the name of the district was changed, to avoid confusion with the Sisaket Province.
Neighboring are from the north clockwise Wiang Sa, Laos, Ban Khok (Uttaradit Province), Na Muen and Rong Kwang (Phrae Province).
