We study the top-Higgs coupling with a CP violating phase ξ at a future multi-TeV muon collider. We focus on processes that are directly sensitive to the top quark Yukawa coupling: $$t$$$\overline{t}$$$$h$, $tbhμν$, and $$t$$$\overline{t}$$$$h$$v$$$\overline{v}$$ with $$h$$ → $$b$$$\overline{b}$$ and semileptonic top decays. At different energies, different processes dominate the cross section, providing complementary information. At and above an energy of $$\mathcal{O}$$(10) TeV, vector boson fusion processes dominate. As we show, in the Standard Model there is destructive interference in the vector boson fusion processes $$t$$$\overline{t}$$$$h$$v$$$\overline{v}$$ and $tbhμν$ between the top quark Yukawa and Higgs-gauge boson couplings. A CP-violating phase changes this interference, and the cross section measurement is very sensitive to the size of the CP-violating angle. Although we find that the cross sections are measured to $$\mathcal{O}$$(50%) statistical uncertainty at 1σ, a 10 and 30 TeV muon collider can bound the CP-violating angle |ξ| ≲ 9.0° and |ξ| ≲ 5.4°, respectively. However, cross section measurements are insensitive to the sign of the CP-violating angle. To determine that the coupling is truly CP violating, observables sensitive to CP-violation must be measured. We find in the $$t$$$\overline{t}$$$$h$ process the azimuthal angle between the $$t$$ + $$\overline{t}$$ plane and the initial state muon+Higgs plane shows good discrimination for ξ = ±0.1π.
