A **simplicial presheaf** is a specific type of presheaf that arises in the context of simplicial sets and homotopy theory. It is a functor from the category of simplicial sets (or a related category) to another category (usually the category of sets, or perhaps some other category of interest such as topological spaces, abelian groups, etc.).
