The invention provides a driving calibration apparatus of an electrostatic MEMS scanning mirror and a driving calibration method thereof The driving calibration method includes the following steps. Different reference voltages are sequentially set to drive a plane mirror of the electrostatic MEMS scanning mirror to swing. Projection positions on a projected surface corresponding to the reference voltages that the laser beam projects to are determined. A driving lookup table is established according to the reference voltages and the corresponding projection positions. Calibrated driving voltages corresponding to ideal projection positions are determined according to the driving lookup table. The pane mirror is driven to swing according to the calibrated driving voltages.
