Abstract: The invention relates to a stackable transport container (30) which has been designed, when in a full condition filled with products, to be stacked with other transport containers on top of each other, or, when in an empty condition, to be placed together with other transport containers inside one another. The transport container has a bottom (2), a front wall (3), a rear wall (4), a left side wall (5) and a right side wall (6) to form a receptacle open towards the top. In the left side wall (5) and in the right side wall (6) respectively, grooves (7, 8) are formed, which respectively have upper groove openings (21, 22) and lower groove stops (10, 11). On the outside of the left side wall (5) and on the outside surface of the right side wall (6) respectively several guide pegs (13) are formed.
