An interlocking fence system is disclosed. Two spaced-apart upright posts ( 8, 10 ) attached to a grade G support a locking rail ( 4 ) with an offset locking aperture ( 26 ) and an alignment aperture ( 32 ) and further support an alignment rail ( 6 ) with an alignment aperture ( 40 ). A picket ( 2 ) has a locking slot ( 22 ) with an edge ( 28 ) of the locking aperture ( 26 ) in locking rail ( 4 ) serving as a tab to restrict axial movement when inserted therein. Alignment aperture ( 32 ) in the locking rail ( 4 ) and alignment aperture ( 40 ) in alignment rail ( 6 ) serve to restrict lateral movement of the picket ( 2 ). To support the rails ( 4, 6 ), retaining slots ( 24, 24 ') in the locking rail ( 4 ) and retaining slots ( 42, 42 ') in the alignment rail ( 6 ) can be retained by an edge ( 38, 50, 38', 50 ') in support apertures ( 12, 14, 16, 18 ) in the posts ( 8 A, 10 A).
