The invention provides a vehicle horn control device and a horn sound reduction control system, which are good in noise inhibition effect in regions where noise needs to be inhibited. The device is used in a vehicle (C) with a horn (43), and is provided with a sound reduction judgment part (301) which is used for judging whether the vehicle is located at a sound reduction region where sound needs to be reduced; a volume control part (302) enables a user to reduce the volume of the horn to be lower than the sound of the horn outside the sound reduction region on the basis that the vehicle is judged by the sound reduction judgment part (301) to be in the sound reduction region. There is no relation to the communication with a warned object. Only if the vehicle is judged to be in the sound reduction region, the sound of the vehicle needs to be reduced. Therefore, a noise inhibition region is set as the sound reduction region in advance, so a good effect of noise inhibition is obtained in a region where noise should be inhibited.
