A niche market is the subset of the market on which a specific product is focused. The market niche defines the product features aimed at satisfying specific market needs, as well as the price range, production quality and the demographics that it is intended to target. It is also a small market segment.

Not every product can be defined by its market niche. The niche market is highly specialized, and aiming to survive among the competition from numerous super companies. Even established companies create products for different niches; Hewlett-Packard has all-in-one machines for printing, scanning and faxing targeted for the home office niche, while at the same time having separate machines with one of these functions for big businesses.

In practice, product vendors and trade businesses are commonly referred to as mainstream providers or narrow demographics niche market providers (colloquially shortened to just niche market providers). Small capital providers usually opt for a niche market with narrow demographics as a measure of increasing their financial gain margins.

The final product quality (low or high) is not dependent on the price elasticity of demand, but the specific needs that the product is aimed to satisfy and, in some cases, aspects of brand recognition (e.g. prestige, practicability, money saving, expensiveness, environmental conscience, or social status). When there are needs or desires with specific and even complex characteristics, the market niche requires specialized suppliers which are capable of meeting such expectations.
