The Mitaka incident (三鷹事件, Mitaka jiken) was an incident that took place in Tokyo, Japan on July 15, 1949, when an unmanned 63 series train with its operating handle tied down drove into Mitaka Station on the Chūō Line, killing six people and injuring 20. The incident remains a mystery, as do the Shimoyama and Matsukawa incidents which occurred around the same time.

The government indicted ten people on a charge of train sabotage resulting in death of the victims, as well as the train's conductor, Keisuke Takeuchi, who was not in the train when it derailed.
