A brand blunder is an error associated with the branding of a product, especially a new product in a new market. Reasons for such slips include the lack of understanding of the language, culture and consumer attitudes in the new market.

There are numerous examples of brand blunders in marketing history; there are also numerous urban legends surrounding brand blunders, where there is little evidence of an actual blunder.

International branding issues Problems with international product branding are often associated with the process of language localisation, in which the product brand name or advertising slogan carries a different meaning in the language of the target market. In addition to linguistic aspects, issues of cultural sensitivity can affect the success of a brand.

This is a risk faced by companies entering a new market. In international marketing, a brand name must be distinctive and easy to pronounce across multiple markets, but it must not have unintended negative or obscene connotations. This risk is usually mitigated by factoring cultural research into a branding strategy.
