A vehicle light distribution control device includes: an illumination device controlled to change a light distribution pattern among high, low and split beam patterns and of which an optical axis direction is controlled; and a control unit. When a vehicle ahead has been detected, the control unit changes the light distribution pattern to the split beam pattern, and controls a cut-off line position of the split beam pattern so as not to irradiate illumination light to the vehicle ahead. When the vehicle ahead becomes undetectable, the control unit maintains the split beam pattern while controlling the cut-off line position in such a manner that the shielded area of the split beam pattern gradually reduces. After the shielded area becomes smaller than or equal to a predetermined reference, the control unit changes the light distribution pattern from the split beam pattern to the high beam pattern.
