We develop the deformation theory of $A_{\infty}$ algebras together with $\infty$-inner products and identify a differential graded Lie algebra that controls the theory. This generalizes the deformation theories of associative algebras, $A_{\infty}$ algebras, associative algebras with inner products, and $A_{\infty}$ algebras with inner products.
