Superspace is an extension of space-time which includes new coordinates with unusual algebraic rules. The nature of superspace is quantum mechanical, because it requires the concept of particle spin. This chapter describes the meaning of superspace and supersymmetry, and shows how these ideas can provide a solution to the naturalness problem. The impact of supersymmetry in the quest for unification is also discussed, from its role in superstring theory to the result of gauge coupling unification. Finally, the chapter describes how experiments at the LHC could discover supersymmetry.
