Provided is a vehicle control device for an amphibious vehicle that can travel with a stable orientation even when the edge of the water consists of uneven terrain or terrain having an inclined surface along a different direction than the direction of travel. A vehicle control device for an amphibious vehicle capable of traveling on land, navigating on the water, and traveling on the edge of the water comprises a jet direction adjuster (15) for adjusting the direction of a jet created by a propeller (11), an orientation detector (31) for detecting the orientation of an amphibious vehicle (1), and a control device (30) for controlling the jet direction adjuster (15) and/or the propeller (11) on the basis of the orientation of the amphibious vehicle (1) detected by the orientation detector (31) when an edge-of-water travel mode is selected.
