A magnetic gate latch device to secure a gate in a locked position to a fence or other barrier to close or block a portal formed therein comprising a latch assembly including a lower latch pin coupled to an upper latch pin actuator by an intermediate interconnecting element mounted to the fence or other barrier adjacent the portal wherein the lower latch pin is normally biased in upper or unlocked position and a keeper assembly including a keeper base affixed to the gate and a keeper arm extending outwardly therefrom having a latch pin recess formed therein with a latch pin positioner comprising a vertically disposed magnet disposed adjacent the latch pin recess such that when the gate is closed the vertically disposed magnet of the latch pin positioner moves the lower latch pin, intermediate interconnecting element and upper latch pin from the normally biased upper or unlocked position to a lower or locked position drawing the latch pin into the latch pin recess against the force of the bias and when as the upper latch pin actuator is moved upwardly the intermediate interconnecting element and the lower latch pin are moved upwardly withdrawing the lower latch pin from the latch pin recess to permit the gate to be opened as the bias maintains the lower latch pin in upper or unlocked position.
