A vertical market (often referred to simply as a "vertical") is a group of similar businesses and customers that engage in trade based on specific and specialized needs. Often, participants in a vertical market are very limited to a subset of a larger industry (a niche market). An example of this sort of market is the market for point-of-sale terminals, which are often designed specifically for similar customers and are not available for purchase to the general public. Vertical marketing can be witnessed at trade shows. The opposite of vertical marketing is horizontal marketing.

Als vertikalen Markt bezeichnet man in der Volkswirtschaft einen Markt, auf dem  Waren und Dienstleistungen aus Geschäftsfeldern einer Wertschöpfungskette einer bestimmten Branche angeboten werden.
