Motivated by periodicity theorems for Real K$K$ ‐theory and Grothendieck–Witt theory and, separately, work of Hori and Walcher on the physics of Landau–Ginzburg orientifolds, we introduce and study categories of Real matrix factorizations. Our main results are generalizations of Knörrer periodicity to categories of Real matrix factorizations. These generalizations are structurally similar to (1,1)‐periodicity for KR$KR$ ‐theory and 4‐periodicity for Grothendieck–Witt theory. We use techniques from Real categorical representation theory, which allow us to incorporate into our main results equivariance for a finite group and discrete torsion twists.
