Facade is a structural design pattern. It provides a single interface to work with complex systems, allowing clients to not have implementation details about these systems, thus simplifying their code, implementing weak coupling between clients and lower-level systems. GoF has a good example of Facade – a compiler of programming languages, providing different clients pursuing different goals with the ability to build code through a single facade-compiler interface.
