A latch assembly for opening and closing a vehicle luggage room may include: a base installed on an end portion of an opening and closing member to open and close a vehicle luggage room; a power conversion member to convert the rotational force of a drive motor into a linear motion; a claw to grip and restrain the striker when the opening and closing member is closed; a pawl to inhibit the rotation of the claw so that the claw maintains a state of having the striker restrained; an error lever installed to rotate with the pawl and configured to rotate so that the pawl is separated from the claw; and a link member to rotate the claw so that the claw grips the striker, when the power conversion member makes the linear motion.
