Umbrella branding (also known as family branding) is a marketing practice involving the use of a single brand name for the sale of two or more related products. Umbrella branding is mainly used by companies with a positive brand equity (value of a brand in a certain marketplace). All products use the same means of identification and lack additional brand names or symbols etc. This marketing practice differs from brand extension in that umbrella branding involves the marketing of similar products, rather than differentiated products, under one brand name. Hence, umbrella branding may be considered as a type of brand extension. The practice of umbrella branding does not disallow a firm to implement different branding approaches for different product lines (e.g. brand extension).

Marketers may increase the chance of success for a new product launch by using a sub-brand name and a parent brand name simultaneously. In the article by Howard Pong Yuen LAM and other co-authors, they report the successful case of using two brand names—dual branding strategy—by practitioners in China for the Minute Maid Orange Pulp juice drink launch:

A suggestive sub-brand name helps consumers recall the key benefits and features of the new product. A suggestive parent brand name communicates the benefits of the product category. A dual branding strategy addresses the problem of using only one brand name for a new product launch. After the successful launch of the first new product by a parent brand, marketers are able to launch other new products under other sub-brand names in the future to meet different consumer needs. Marketers may use the same parent brand to introduce different products to build scale for the brand, and are able to clearly differentiate the different product offerings under different sub-brand names. If a company acquires a brand from another company, a marketer may position the acquired brand as a sub-brand under the parent brand if the marketer has defined the business scope of the parent brand broadly enough and with a suggestive parent brand name.

Umbrella branding is used to provide uniformity to certain product lines by grouping them under a single brand name, making them more easily identifiable and hence enhancing their marketability. All products under the same corporate umbrella (masterbrand providing structure and credibility to other products of the corporation) are expected to have uniform quality and user experience (e.g. All products carrying the parent brand must be of the same high quality standards).

Factors that may determine the impact of umbrella branding include:

Various theories attempt to explain a consumer's decisions and judgements during product purchasing that cause umbrella branding to be a successful marketing strategy.

The categorization theory is based upon the notion that consumers tend to categorize products by associating them to brands and their past experiences with those particular brands (stored in their category memory) in order to evade the initial confusion caused by the extensive choice of products they are presented with. New information on certain products are categorized into various sections such as product class (e.g. beverage) and brand (e.g. Coca-Cola) and then stored. Afterwards, consumers evaluate the product quality through past experiences with the brand's products as well as the brand equity.

This theory also explains for the popularity of umbrella branding. Consumers tend to evaluate new products not only by positive brand equity but also if the brand's concept is consistent with their extended products. For instance, assuming that the consumer had satisfactory past experiences with the company's products, if Apple Inc. would develop and sell a new version of a Macbook, consumers would deem it more reliable and potentially of superior quality rather than if Apple would produce a new beverage due to Apple's past product line.
