We assess the sensitivity of future lepton colliders to weakly coupled vector\ndark portals (aka `` Z' bosons'') with masses ranging from tens of GeV to a\nfew TeV. Our analysis focuses on dark photons and L\μ - L\τ gauge\nbosons. We consider both visible and invisible decay channels. We demonstrate\nthat both high energy \μ colliders and future e+e- colliders, using\nthe FCC-ee Z-pole and ZH operation modes as a benchmark, offer significant\nimprovements in sensitivity. We find that both colliders can enhance the\nsensitivity to L\μ - L\τ bosons (for both visible and invisible\ndecays) and to invisibly decaying dark photons by 1--2 orders of magnitude\nacross the relevant mass range. Furthermore, we study the impact of forward \n\μ detectors at the \μ -collider on the sensitivity to both models.\n
