Chalcorana parvaccola is a species of "true frog" in the family Ranidae. It is endemic to Sumatra, Indonesia.

The specific name parvaccola is derived from Latin parvus meaning small and accola meaning neighbor, and refers to this species being smaller than its "neighbor", the related Sumatran species Chalcorana rufipes.
