Ban Mo (Thai: บ้านหมอ, pronounced [bâːn mɔ̌ː]) is a district (amphoe) in the northwestern part of Saraburi province, central Thailand.

After the Buddha footprint near Saraburi was found and a temple was built, King Songtham hired Dutch engineers to build a road from Tha Ruea to Wat Phra Phutthabat to make the pilgrimage there easier. Elephants did the heavy lifting. When the elephants got sick, they were cured at Wat Khok (later called Wat Khok Ban Mo and Wat Ban Mo finally), which thus gave the district its name. Because Ban Mo literally means "home of doctor".

Neighboring districts are (from the west clockwise) Don Phut, Nong Don, Phra Phutthabat, Sao Hai of Saraburi Province, and Tha Ruea of Ayutthaya province.

The district is divided into nine sub-districts (tambons).
