The notion of \(C^{(2)}_{N+1}\) Ruijsenaars-Schneider models is defined and their Lax formulation is considered. The models are obtained by a particular folding of the \(A_{2N+1}\) systems. Their commuting Hamiltonians are linear combinations of Koornwinder-van Diejen ``external fields'' Ruijsenaars-Schneider models for specific values of the exponential one-body couplings but with the most general two double-poles structure as opposed to the formerly studied \(BC_N\) case.
