A modular multi-computer monitor stand system for multi-computer monitor setups is disclosed. The stand system provides various discrete interlocking components including a rail, slide members, elongated legs, base members and mounting plates that modularly interconnect to form an upright stand capable of holding multiple computer monitors thereon. The rail includes various grooves for slidably receiving the slide members. The slide members include projections slidably engageable with the grooves of the elongated rail and interlocking regions detachably engageable with the base members and the mounting plates. The base members include interlocking receptacles detachably engageable with the elongated legs and interlocking regions detachably engageable with the interlocking regions of the slide members. The mounting plates include interlocking regions detachably engageable with the interlocking regions of the slide members and universally positioned apertures for fastening the mounting plate to any type of computer monitor.
