“The Portable, Collapsible, Free-Standing Bar” is an improved portable and compact free-standing bar. Its distinctive features include its ease of assembly, stability, well-crafted finished-wood appearance, collapsible design, compact storage, and ease of transport and shipping. It can be assembled easily without tools, and is designed meticulously to minimize weight, maximize stability and portability, and minimize the space that it occupies when collapsed and stored. These user-friendly features make the bar a useful contribution to an improved social experience in many venues, including weddings, tailgate parties, etc. The bar design is comprised of a bartop formed by a plurality of selectively adjoining bartop pieces and a plurality of frames pivotally interlocked by at least one hinge, which allow the bar to be collapsed into a space-efficient unit on wheels for storage, transport, or shipping. The bar can be alternately be assembled in an open position for using the bar and disassembled to a closed position for transporting or storing the bar, wherein in the closed position the bartop pieces are nested within the frames, and wherein said frames are collapsed to a compact folded configuration forming a parallelepiped. Another aspect of the bar's design is a swivel footing rotatably attached to a base support of each frame that adds significant stability to the bar when in the open position without adding to the width, or overall size of the collapsed bar is the closed position.
