Sam Ngam (Thai: สามง่าม, in Thai pronounced as /sǎːm ŋâːm/) is a district (amphoe) in the northwestern part of Phichit province, central Thailand.
Originally Sam Ngam was a tambon of Tha Luang district. On 1 March 1939 the government separated Tambons Sam Ngam, Rang Nok, Wang Chik, Phai Rop, Ban Na, and Noen Po from Mueang Phichit District, Kamphaeng Din and Hat Kruat from Bang Krathum district, Phitsanulok province to establish the new district, Sam Ngam.[1] Later in 1943 Tambon Wang Chik and Phai Rop were assigned to Pho Prathap Chang District.
Neighboring districts are (from the east clockwise) Mueang Phichit, Pho Prathap Chang of Phichit Province, Bueng Samakkhi, Sai Thong Watthana, Sai Ngam of Kamphaeng Phet province, Wachirabarami of Phichit Province, Bang Rakam and Bang Krathum of Phitsanulok province.
Sam Ngam is divided into five sub-districts (tambons), which are further subdivided into 80 administrative villages (mubans).
