A marketing plan is a written document that details the necessary actions to achieve one or more marketing objectives. It can be for a product or service, a brand, or a product line. It can cover one year (referred to as an annual marketing plan), or cover up to 5 years.

A marketing plan may be part of an overall business plan. Solid marketing strategy is the foundation of a well-written marketing plan. While a marketing plan contains a list of actions, a marketing plan without a sound strategic foundation is of little use.
