A headlight control apparatus for controlling an irradiation angle of a headlight of a vehicle based on a pitch angle includes a height sensor and a camera. The height sensor detects a displacement amount of a spring upper member with respect to a rotation axis of the vehicle as a contraction length. The apparatus obtains an infinity point correlation value based on an infinity point position in the image obtained by the camera in a vertical direction. When a predetermined condition is satisfied, the apparatus obtains a standard pitch angle based on the contraction length and obtains the infinity point correlation value at the present time as a standard infinity point correlation value. When the condition is not satisfied, the apparatus obtains the pitch angle based on the standard pitch angle, the standard infinity point correlation value, and the infinity point correlation value at the present time.
