Top and electroweak physics at the LHeC and the FCC-eh

Highlights of the rich electroweak and top quark physics program at future LHeC and FCC-eh colliders are presented. The studies involve high precision analyses of the weak mixing angle, vector and axial-vector weak neutral couplings of light quarks, the polarization asymmetry in neutral current scattering, the CKM matrix element $\lvert V_{tb} \rvert$ and anomalous $Wtb$ couplings, flavor-changing neutral current $tu \gamma$ couplings, and flavor-changing neutral current $t \rightarrow uH$ branching ratios.
