Compactible wagons are provided having at least two operational configurations. The compactible wagon has a first unfolded configuration where the first and second set of wheels are spaced apart by a horizontal platform, and where the wagon has one or more sidewalls, and at least a second compacted configuration where the horizontal platform is folded into a vertical configuration and the first and second set of wheels are disposed next to each other. The compactible wagon can have one or more additional configurations, including at least an unfolded configuration without sidewalls and/or an extended configuration where one or more of the sidewall are disposed to extend the surface area of the horizontal platform of the wagon. Many different rigid and flexible sidewalls may be used with the wagon.
