MVC is a design pattern used to decouple user interface (view), data (model), and application logic (controller). This pattern helps to achieve separation of concerns. 

The Model-View-Controller (MVC) is an architectural pattern that separates an application into three main logical components: the model, the view, and the controller. 

Using the MVC pattern for websites, requests are routed to a Controller that is responsible for working with the Model and View to perform actions and/or retrieve data.
