In the next decades, ultra-high-energy neutrinos in the EeV energy range willbe potentially detected by next-generation neutrino telescopes. Although theirprimary goals are to observe cosmogenic neutrinos and to gain insight intoextreme astrophysical environments, they can also indirectly probe the natureof dark matter. In this paper, we study the projected sensitivity of up-comingneutrino radio telescopes, such as RNO-G, GRAND and IceCube-gen2 radio array,to decaying dark matter scenarios. We investigate different dark matterdecaying channels and masses, from $10^7$ to $10^{15}$ GeV. By assuming theobservation of cosmogenic or newborn pulsar neutrinos, we forecast conservativeconstraints on the lifetime of heavy dark matter particles. We find that theselimits are competitive with and highly complementary to previousmulti-messenger analyses.
