International marketing (IM) or global marketing refers to marketing carried out by companies overseas or across national borderlines. This strategy uses an extension of the techniques used in the home country of a firm. It refers to the firm-level marketing practices across the border including market identification and targeting, entry mode selection, marketing mix, and strategic decisions to compete in international markets.According to the American Marketing Association (AMA) "international marketing is the multinational process of planning and executing the conception, pricing, promotion and distribution of ideas, goods, and services to create exchanges that satisfy individual and organizational objectives." In contrast to the definition of marketing only the word multinational has been added. In simple words international marketing is the application of marketing principles to across national boundaries. However, there is a crossover between what is commonly expressed as international marketing and global marketing, which is a similar term.

The intersection is the result of the process of internationalization. Many American and European authors see international marketing as a simple extension of exporting, whereby the marketing mix 4P's is simply adapted in some way to take into account differences in consumers and segments. It then follows that global marketing takes a more standardised approach to world markets and focuses upon sameness, in other words the similarities in consumers and segments.
