A mounting apparatus for a sliding drawer mechanism is disclosed. The mounting apparatus includes a bracket, a latching member and a mounting piece. The bracket includes a side plate, and the side plate defines a limiting hole. The latching member is secured to the sliding drawer mechanism and includes an elastic latching portion. The mounting piece extends from the sliding drawer mechanism, and a mounting post protrudes from the mounting piece. The mounting post is received in the limiting hole to prevent the sliding drawer mechanism from sliding along a direction substantially parallel to the side plate, and the elastic latching portion and the mounting piece are located on two opposite sides of the side plate, to prevent the sliding drawer mechanism from sliding along a direction substantially perpendicular to the side plate.
