The vibration damping device for an elevator rope includes: an actuator, which is placed in a hoistway, and is configured to generate a forced displacement in response to a drive input and apply a force generated by the forced displacement to an elevator rope; a lateral vibration measuring unit configured to measure a lateral vibration generated in the elevator rope and output the measured lateral vibration as lateral vibration information; a lateral vibration estimation unit configured to estimate a lateral vibration of the elevator rope at a position of the actuator based on the lateral vibration information and output the lateral vibration as an estimated lateral vibration; and an actuator drive unit configured to output the drive input to the actuator to drive the actuator so that the forced displacement has a phase reverse to a phase of the estimated lateral vibration output from the lateral vibration estimation unit.
