An inter-vehicle distance control device is provided. In this control device, an inter-vehicle distance detecting section detects an inter-vehicle distance between an own vehicle and a preceding vehicle traveling in front of the own vehicle. A laterally adjacent vehicle detecting section detects another vehicle present beside the own vehicle. A cut-in detecting section judges whether or not a cut-in by the other vehicle detected by the laterally adjacent vehicle detecting section is likely to occur, before the other vehicle cuts in between the own vehicle and the preceding vehicle. An inter-vehicle distance adjusting section performs an inter-vehicle distance extension adjustment to increase the inter-vehicle distance when the cut-in detecting section judges that a cut-in is likely to occur. An inter-vehicle distance control section controls the inter-vehicle distance based on information from the inter-vehicle distance adjusting section.
