This paper introduces Nitsche's method for numerical approximation of the Kirchhoff-Love plate equation with general Robin-type boundary conditions. The method is analyzed by providing a priori and a posteriori error estimates in mesh-dependent norms. Several numerical examples are presented to validate the approach and demonstrate its properties.
