A hinge lock for locking a door leaf with respect to a door frame and for pivoting the door leaf with respect to the door frame. The hinge lock has a first hinge element for arranging on the door leaf and a second hinge element for arranging on the door frame. The first hinge element and the second hinge element can be locked with respect to one another by means of a bolt which can be moved back and forth in a locking direction between an unlocking position and a locking position and the locking position by means of a drive rod which can be moved transversely to the locking direction. The disclosure further relates to a door having a hinge lock.
