Embodiments of the present invention provide a split-screen display method and an electronic device. The method includes: An electronic device displays a display interface corresponding to a first task on a display when running a first application to execute the first task; receives, on the display interface corresponding to the first task, a first operation used to enable a second task; and enables a split-screen display mode in response to the first operation. Compared with that in the conventional technology, in the embodiments of the present invention, the split-screen mode can be triggered without an additional manual operation of a user. This achieves a technical effect of triggering, based on a task, an electronic device to enter a split-screen display mode, so that intelligence of the electronic device is improved.
