We study the algebraic properties of soft sets in a hypermodule structure. The concepts of soft hypermodules and soft sub-hypermodules are introduced, and some basic properties are investigated. Furthermore, we define homomorphism and isomorphism of soft hypermodules, and derive three isomorphism theorems of soft hypermodules. By using normal fuzzy sub-hypermodules, three fuzzy isomorphism theorems of soft hypermodules are established.
