A foldable electronic device having multiple screens is provided. The foldable electronic device includes a first screen, a worm rod, a moving member, at least one second screen, and at least one linking rod. The worm rod is rotatably disposed on the first screen. The moving member is coupled to the worm rod to move along the worm rod when the worm rod rotates. The second screen is movably disposed on the first screen. The linking rod is pivotally connected between the moving member and the second screen. When the moving part moves along the worm rod, the second screen is driven to move away from or closed to the worm rod by the linking rod, so that the second screen moves out of the first screen or is accommodated behind the first screen.
