In this paper, we propose a new four-component Camassa–Holm-type system. The Lax pair and infinitely many conservation laws of this system are constructed. Bi-Hamiltonian structures and N-peakon solutions of some prototypical equations in this system are considered. In particular, the “W/M”-shape peakon solutions are obtained.
