A shelving unit includes a support frame and a plurality of support boards each mounted on the support frame. The support frame includes a front support bracket, a back board located opposite to the front support bracket, four first connecting tubes each having a first end connected with the respective corner of the front support bracket, and four second connecting tubes each having a first end connected with a second end of the respective first connecting tube and a second end connected with the respective corner of the back board. Thus, the shelving unit can be assembled and disassembled without using tools, thereby facilitating assembling the shelving unit. In addition, the shelving unit can be folded into a smaller overall volume to reduce the cost of packaging, transportation and storage of the shelving unit.
