The invention provides a controller and a control method for an internal combustion engine. The controller for an internal combustion engine is configured to control the internal combustion engine. The internal combustion engine includes an in-cylinder injection valve, an ignition device, an exhaust passage, and a three-way catalyst. The controller includes a fuel introduction processor configuredto execute a fuel introduction process of introducing air-fuel mixture of fuel and air, which has been introduced into a cylinder, into the exhaust passage without burning the air-fuel mixture in thecylinder. The fuel introduction processor is configured to execute the fuel introduction process in a state in which only a port injection valve of the in-cylinder injection valve and the port injection valve performs fuel injection. 提供一种内燃机的控制装置及控制方法。内燃机的控制装置构成为控制内燃机。内燃机具备缸内喷射阀、端口喷射阀、点火装置、排气通路及三元催化剂装置。控制装置具备燃料导入处理部。燃料导入处理部构成为，实施使导入到汽缸的燃料与空气的混合气不在该汽缸内燃烧而向排气通路导入的燃料导入处理。燃料导入处理部构成为，在仅缸内喷射阀及端口喷射阀中的端口喷射阀执行燃料喷射的状态下实施燃料导入处理。
