We introduce the shifted quantum affine algebras. They map homomorphically into the quantized K-theoretic Coulomb branches of 3dN=4 SUSY quiver gauge theories. In type A, they are endowed with a coproduct, and they act on the equivariant K-theory of parabolic Laumon spaces. In type A1, they are closely related to the type A open relativistic quantum Toda system.
