In physics the term Wilson loop refers to an observable in gauge field theory given by the holonomy of the given gauge field connection along a fixed curve.
In higher gauge theory one correspondingly has observables given by higher holonomy around higher dimensional manifolds, such as surfaces etc. These are hence sometimes called “Wilson surfaces” etc.
