The Battle of Sông Bé was a major action between the Viet Cong (VC) and Army of the Republic of Vietnam (ARVN) in May 1965. Planned as a major show of force against the ARVN forces, the VC attempted to capture Sông Bé and the capital of Phước Long Province. However, ARVN forces in the area rallied and re-took the town by the end of the second day of combat.
