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

The first element bang (Thai: บาง) means 'village' or 'settlement'. The second element krathum (Thai: กระทุ่ม) means 'bur-flower tree' (Anthocephalus chinensis).

Bang Krathum's topography consists of flat, fertile lowlands. Clockwise from the north, the subdistrict is bordered by Wang Nam Khu (of Mueang Phitsanulok District), Tha Tan, Nakhon Pa Mak, Phai Lom, Ta Fo (of Mueang Phichit District in Phichit Province), Sanam Khli, Khok Salut and Ban Rai. Bang Krathum lies in the Nan Basin, which is part of the Chao Phraya Watershed. The town of Ban Bang Krathum is on the tambon's chief watercourse, a canal which winds through farms heading north-east to Ban Bang Kranoi in Nakhon Pa Mak, where it joins the Wang Thong River. The canal splits once between Ban Bang Krathum and Ban Bang Krathum, where a smaller branch leads due north to Ban Bueng Lam in Nakhon Pa Mak.

The subdistrict is divided into 11 smaller divisions called (muban), which roughly correspond to the six villages in Bang Krathum. Bang Krathum is administered by a Tambon administrative organization (TAO). The mubans in Bang Krathum are enumerated as follows:
