A hammock support is provided that includes an arched structure supported by tripod leg supports. The arched support is preferably a truss structure that provides multiple attachment points to support a hammock bed for varying the types, lengths, and heights of hammocks. In some embodiments, the arched truss structure includes multiple interlocked truss sections that can be assembled and disassembled without tools. The tripod leg supports provide stability for use in wet, uneven, or otherwise inhospitable terrain. The arched structure provides attachment locations for one or more accessories, such as mosquito netting, tents, tables, drink holders, lights, and other accessories. Additionally, the hammock support assembly of the invention is adapted to be used with one or more hammock support assemblies to create larger structures to create tents or bivouacs for camping or emergency shelter.
