Office supplies is the generic term that refers to all supplies regularly used in offices by businesses and other organizations, from private citizens to governments, who works with the collection, refinement, and output of information (colloquially referred to as "paper work").

The term includes small, expendable, daily use items such as paper clips, staples, hole punches, binders and laminators, writing utensils and paper, but also encompasses higher-cost equipment like computers, printers, fax machines, photocopiers and cash registers, as well as office furniture such as cubicles or armoire desks. Two very common medium-to-high-cost office equipment items before the advent of suitably priced word processing machines and PCs in the 1970s and 1980s were typewriters and adding machines.
