A glow plug energization control apparatus is provided which includes a power supply working to supply electric power to a glow plug mounted in an internal combustion engine, an on-off switch working to produce a control trigger signal when turned on, and a controller including a microcomputer. The microcomputer is responsive to the control trigger signal to control supply of the electric power from the power supply to energize the glow plug. The microcomputer works to monitor an off-on interval from turning off to turning on of the on-off switch and control an amount of energization of the glow plug as a function of the off-on interval, thereby avoiding overheating of the glow plug.
