An overhead storage system for attachment to a ceiling includes a hollow housing, frame and a pair of pivots pivotally attaching a rear end of the frame to a rear end of the housing so that the frame pivots between a storage position wherein the frame is disposed generally coplanar with a ceiling surface and an access position wherein the frame is disposed at a predetermined angle relative to the ceiling surface. A latch assembly releasably secures the frame in the storage position. There is a storage container which is telescopically movable through an open front end of the frame between a retracted position wherein the storage container is substantially disposed within confines of the frame and an extended position wherein a front end of the storage container is disposed a predetermined distance from the open end of the frame.
