Wang Thong (Thai: วังทอง, pronounced [wāŋ tʰɔ̄ːŋ]) is a district (amphoe) of Phitsanulok province, central Thailand.

In 1928 the government created Bang Krathum district, and tambons Phai Lom, Noen Kum, and Nakhon Pa Mak were assigned to it.

[1] Tambons Kaeng Sopha and Ban Klang of Nakhon Thai district were reassigned to Wang Thong.

When the buildings on the east bank of Wang Thong River were washed away by a flood, the district office relocated to its present site.

In 1931 the district name was changed to Pa Mak, finally designated as Wang Thong in 1939.
