To provide a surgical microscope comprising a microscope collimator for enabling the operator to easily recognize the swivel center of the microscope body regardless of what position the microscope body moves for easy setting of the swivel center point of the microscope body, a surgical microscope pivotally supporting a microscope body having, an observation optical system with one point on an observation optical axis of the microscope body as the swivel center. The surgical microscope comprises index projectors as swivel center visible indicators being capable of recognizing the swivel center. This configuration enables the operator to easily recognize the swivel center of the microscope body for easy setting of the swivel center point of the microscope body. Also, to provide a surgical microscope which does not disturb an operator who handles the microscope or performs an operation and also enables the operator to easily observe at every angle from every direction for improving operability, the surgical microscope is capable of changing an observation angle and an observation direction with a gaze point P on an observation optical axis a of a microscope body having an observation optical system as a rotation center. A base unit that can be moved in X, Y, and Z directions is disposed at a position relative to the microscope body and a swivel base rotatable with the gaze point P as a rotation center is installed above the base unit.
