A handyman, also known as a fixer, handyperson or handyworker, maintenance worker, maintenance man, repairman, repair worker, or repair technician, is a person who is knowledgeable in skills such as basic carpentry, plumbing, minor electrical wiring and property maintenance. They can perform a wide range of repairs, typically for keeping buildings, shops or equipment around the home in good condition. These tasks include trade skills, repair work, maintenance work, are both interior and exterior, and are sometimes described as "side work", "odd jobs" or "fix-up tasks". Specifically, these jobs could be light plumbing jobs such as fixing a leaky toilet or light electric jobs such as changing a light fixture or bulb.

The term handyman increasingly describes a paid worker, but it also includes non-paid homeowners or do-it-yourselfers. The term handyman is also occasionally applied as an adjective to describe politicians or business leaders who make substantial organizational changes, such as overhauling a business structure or administrative division.

Many people can do common household repairs. There are resources on the Internet, as well as do-it-yourself guide books, with instructions about how to complete a wide range of projects. Sometimes the fix-it skill is seen as genetic, and people lacking such skills are said to "lack the handy-man gene". One trend is that fewer homeowners are inclined to do fix-up jobs, perhaps because of time constraints, perhaps because of lack of interest; one reporter commented "my family's fix-it gene petered out before it reached my generation."

Historically being a handyman was considered a less prestigious occupation than a specialist such as a plumber, electrician, or carpenter. With the emergence of large national chains, there have been efforts to change that perception by emphasizing the professionalism of the trade and that a handyman is a technician with multiple skills and a wide range of knowledge. Handyman tools are sometimes useful in unusual situations. For example, when a proper cranial drill was not available, an Australian doctor used a handyman's drill in 2009 to open a hole in the head of a 13-year-old boy to relieve pressure after a brain injury; the boy's life was saved.

Tasks range from minor to major, from unskilled to highly skilled, and include painting, drywall repair, remodeling, minor plumbing work, minor electrical work, household carpentry, sheetrock, crown moulding, and furniture assembly.

An estimate was that in 2003, the market for home-maintenance and repair spending was up 14% from 2001 to 2003. Another estimate was that the market in the United States was $126 billion and was increasing by about 4% annually. American homes are aging; one estimate was that in 2007, more than half of all homes are older than 25 years. And, as populations worldwide tend to become older, on average, and since increasingly elderly people will be less inclined and able to maintain their homes, it is likely that demand for handyman services will grow.^{[original research?]}

Many towns have handymen who work part-time, for friends or family or neighbors, who are skilled in a variety of tasks. Sometimes they advertise in newspapers or online. They vary in quality, professionalism, skill level, and price. Contractors often criticize the work of previous contractors, and this practice is not limited to handymen, but to all trades. Handymen have advertised their services through flyers and mailings; in addition, free websites such as Craigslist and SkillSlate help customers and handymen find each other.

In 2009, there were national handyman service firms which handle such nationwide tasks as public relations, marketing, advertising, and signage, but sell specific territories to franchise owners. A franchise contract typically gives a franchise owner the exclusive right to take service calls within a given geographical area. The websites of these firms put possible customers in touch with local owners, which have handymen and trucks. Customers call the local numbers. Typically, these firms charge around $100/hour, although fees vary by locality and time of year. In many parts of the world, there are professional handyworker firms that do small home or commercial projects which claim possible advantages such as having workers who are insured and licensed. Their branch offices schedule service appointments for full-time and part-time handymen to visit and make repairs, and sometimes coordinate with sub-contractors.
