A handyman, also known as a fixer, handyperson or handyworker, maintenance worker, repair worker, or repair technician, is a person skilled at a wide range of repairs, typically for keeping buildings, shops or equipment around the home in good repair. 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 sometimes become useful in different places: 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.
