In this talk we present some ideas on the top physics program at the future electron proton colliders LHeC and FCC-eh. Mentioned topics involve but are not limited to the top structure function, top parton distribution functions,
top spin polarization, top electric charge, measurement of $\rm V_{tb}$, $\rm V_{ts}$ and $\rm V_{td}$ CKM matrix elements, anomalous $\rm tt\gamma$, ttZ, tbW, $\rm tq\gamma$ and tuh couplings and the CP phase of the tth coupling. The study of flavor changing neutral current tuh couplings and the measurement of $\rm V_{td(s)}$ CKM matrix elements are highlighted to show current progress in the top sector.
