Khok Salud (Thai: โคกสลุด) is a subdistrict (tambon) in the Bang Krathum District of Phitsanulok Province, Thailand.

Khok Salut is bounded to the north by Ban Rai, to the east by Bang Krathum, to the south by Sanam Khli, and to the west by Phichit Province. Most of Khok Salut lies in the Nan Basin, although a narrow strip of land on the west side of the subdistrict lies in the Yom Basin. Both basins are part of the Chao Phraya Watershed. The Nan River flows through Khok Salut.

The subdistrict is divided into 10 smaller divisions called (mubans), which roughly correspond to the villages in Khok Salut. There are six villages, several of which occupy multiple mubans. Khok Salut is administered by a tambon administrative organization (TAO). The mubans in Khok Salut are enumerated as follows:
