An anti-dumpling pallet structure includes a pallet body and at least one supporting module. At least one chamber is formed inside the pallet body. The at least one supporting module includes a first supporting member and a second supporting member. The first supporting member and the second supporting member are movably connected to the pallet body. The first supporting member and the second supporting member protrude from the pallet body to provide support for preventing the pallet body acted by an external force from falling over when the at least one supporting module is located at a first position relative to the pallet body, and the first supporting member and the second supporting member are received inside the at least one chamber when the at least one supporting module is located at a second position relative to the pallet body.
