Pang Sila Thong (Thai: ปางศิลาทอง, pronounced [pāːŋ sì.lāː tʰɔ̄ːŋ]) is the southwesternmost district (amphoe) of Kamphaeng Phet province, central Thailand.

The government split tambons Pang Ta Wai, Hin Dat, and Pho Thong from Khlong Khlung district and created the minor district (king amphoe) Pang Sila Thong on 31 May 1993.

Neighboring districts are (from the north clockwise): Khlong Lan, Khlong Khlung, Khanu Woralaksaburi of Kamphaeng Phet Province; Mae Wong of Nakhon Sawan province and Umphang of Tak province.

The district is divided into three subdistricts (tambons), which are further subdivided into 42 villages (mubans).
