An interlocking latch guard for obstructing and resisting the unauthorized opening of an inwardly opening locked door comprises a frame channel mountable on the outside surface of a door frame, and a door channel mountable on the outside surface of a door. The frame channel has a pair of spaced-apart, parallel side flanges, and a front flange directed perpendicularly to the side flanges such that the frame channel has a generally U-shaped cross-section. The door channel includes at least one interlocking flange, and a back flange directed perpendicularly to the interlocking flange. When the door is closed and locked, and the channels are appropriately mounted by fasteners, the interlocking flange of the door channel protrudes substantially parallel to and in between the side flanges of the frame channel, thereby restricting or blocking access to the fasteners. In this configuration, the interlocking latch guard protects the latch from being tampered with by the use of tools, such as jimmy bars, flexible strips, or devices used to spread the door frame to disengage the latch from the frame.
