An exhaust gas cleaning apparatus for an internal combustion engine that is mounted on a vehicle includes an exhaust passage that is connected to the internal combustion engine, a filter that collects particulate matter in exhaust gas, an NOreducing catalyst, a dosing valve that injects urea solution into the exhaust passage, and a controller that performs a filter regeneration process in response to a request for the filter regeneration process. The filter regeneration process includes a first filter regeneration process that is performed during an idle operation of the internal combustion engine and a second filter regeneration process that is performed with the vehicle traveling. When the first filter regeneration process has been performed for a predetermined number of times without being intervened by the second filter regeneration process, the controller does not perform the first filter regeneration process even when a request for the filter regeneration process is made.
