A vehicle wiper control device. When a masking object sensor detects that a masking object is adhered to an outer surface of a window part during execution of automatic wiper control, removal of the masking object performed by a passenger moving to the outside of the vehicle is prevented from becoming difficult due to action of the wiper. Automatic wiper control prohibiting means prohibits execution of automatic wiper control when vehicle stop detecting means detects that a vehicle is stopping and a masking object detecting part determines that a masking object is adhered to the outer surfaceof a window part. When the vehicle stop detecting means detects that the vehicle is stopping and a state of the masking object detecting part is changed from a state where the masking object detectingpart detects that the masking object is adhered to the outer surface of the window part to a state where the masking object detecting part detects that the masking object is not adhered to the outersurface of the window part at a changing time, the automatic wiper control prohibiting means prohibits the execution of said automatic wiper control for a predetermined period of time from the changing time.
