For use with a ladder having opposed side rails and spaced apart rungs extending between the side rails, a removable shelf comprising: a base member of length less than the spacing between the ladder side rails, the base member providing a flat upper surface, the width being sufficient to afford a step, seat or shelf, the base portion having a forward edge and a rearward edge; an upward extending hanger member having an upper end and a lower end, the lower end being pivotally attached to said base member adjacent the rearward edge thereof, the upper end having a hook portion for removably and pivotally engaging a ladder rung; a downwardly extending support member having an upper end and a lower end, the upper end being pivotally attached to said base member adjacent the forward edge thereof, the lower end having means for removably and pivotally engaging and ladder rung; and a retaining bar having a forward end and a rearward end, the bar being pivotally attached below the base member and adjacent the rearward edge thereof, the retaining bar having means intermediate the ends thereof for removably engaging a ladder rung and for disengaging the ladder rung when the forward end is upwardly pivoted, the apparatus being dimensioned whereby the base member may be supported immediately above a ladder rung with the upper end of the hanger member attached to the next adjacent upper ladder rung and lower end of the support member attached to the next adjacent lower ring, said support bar serving to retain the base member in at least one preselected position relative to the rung immediately below it.
