A variable valve timing control apparatus for an internal combustion engine having a crankshaft and a camshaft, the variable valve timing control apparatus including a hydraulic variable valve timing device, an intermediate lock mechanism, and an oil pressure control device. The control apparatus learns an intermediate lock position to obtain a learning value of the intermediate lock position when the intermediate lock mechanism locks the VCT phase at the intermediate lock position. The control apparatus computes an actual VCT phase based on the learning value of the intermediate lock position. The control apparatus computes a target VCT phase in accordance with an operational condition of the engine based on the learning value of the intermediate lock position. The control apparatus controls a control amount of the oil pressure control device such that the actual VCT phase becomes the target VCT phase.
