  "abstract": "We investigate the sensitivity to TeV-scale heavy Majorana neutrinos at a future muon-proton collider with $$\\sqrt{s}=5.3$$ TeV, based on 1 TeV muon and 7 TeV proton beams. We focus on the lepton-number-violating (LNV) process $$\\mu ^- p \\rightarrow jN$$, followed by $$N\\rightarrow \\mu ^+W^-\\rightarrow \\mu ^+J$$, leading to the characteristic final state $$j\\mu ^+J$$. Here, j denotes the associated light jet from heavy-neutrino production, while J denotes the fat jet originating from the hadronic d ecay of the highly boosted W boson. This topology provides a clean experimental signature with strongly suppressed Standard Model backgrounds. A comprehensive signal and background analysis is performed using parton showering, fast detector simulation, and dedicated fat-jet reconstruction. We derive the projected $$2\\sigma $$ exclusion limits on the muon-flavor mixing parameter $$|V_{\\mu N}|^2$$ for integrated luminosities of 100 fb$$^{-1}$$ and 1 ab$$^{-1}$$. For heavy-neutrino masses in the range $$1~\\textrm{TeV}\\le m_N\\le 3~\\textrm{TeV}$$, the projected upper limits on $$|V_{\\mu N}|^2$$ range from $$2.6\\times 10^{-6}$$ to $$5.9\\times 10^{-5}$$ at 1 ab$$^{-1}$$. These results show that a future $$\\mu p$$ collider can provide competitive and complementary sensitivity to TeV-scale heavy Majorana neutrinos compared with other proposed high-energy facilities.",
