Embodiments of the present application provide an application program uninstallation method and apparatus. The method comprises: receiving an uninstallation instruction for a target application program (S101); deleting a specific directory in a local device to which the target application program corresponds, according to the received uninstallation instruction (S102); extracting an identifier of the target application program (S103); searching a local pre-set directory residual database to determine whether there exist any directory data that correspond to the identifier (S104), the directory data comprising at least a directory path; if such directory data exist, deleting a directory in the local device to which the directory path found corresponds, according to the search result (S105). By applying the embodiments of the present application, when the specific directory corresponding to the uninstalled application program is deleted, other directories, other than the specific directory, to which the uninstalled application program corresponds are also deleted, so that after the uninstall of the application program is completed, file residue is avoided, and the occupation of the device storage space is reduced.
