A double-door lock assembly includes a first lock and a second lock which are respectively mounted on a first door and a second door. The double-door lock assembly utilizes a first linkage member of the first lock to connect a second linkage member of the second lock to allow the first and second locks to co-operate. Hence the first and second doors can be opened or closed simultaneously in the same direction.
