In an injection quantity control apparatus for an internal combustion engine, a command value of an injection quantity is calculated based on a command injection quantity. After that, an injector provided for each cylinder is actuated so that a fuel injection quantity supplied into each of the cylinders is controlled in accordance with the command value. In that process, a correction amount learned in a learning control is reflected in the calculation of the command injection quantity or the command value. The learning control is performed while a cylinder cut-off control is performed when a predetermined engine operating condition is met. In the cylinder cut-off control, all of the cylinders are divided into K groups and the cylinder cut-off control is performed with the cylinders of a group in the K groups.
