Saint-Blimont (French pronunciation: [sɛ̃ blimɔ̃]) is a commune in the Somme department in Hauts-de-France in northern France.

The commune is situated 12 miles (19 km) west of Abbeville, on the D106 road. Sitting squarely between the industrial Vimeu region and the tourist regions of Picardie.

Closely linked with Saint-Valery-sur-Somme. The monk evangelist Saint Valery healed Blimond around 615, who succeeded him as head of the abbey at Saint-Valery-sur-Somme.
