The essence, content, and principles of the term "innovative marketing" have been defined. We propose a classification of varieties of innovative marketing depending on their functional belonging. Practical implications. Results of the study can be used in the development of proposals related to the effective formation and application of marketing at an enterprise. Originality/Value.
