Transparent conductive indium tin oxide (ITO) thin films, electrochemically intercalated with sodium or other cations, exhibit sharp superconducting transitions with a zero resistance onset at 5 K. The transition temperature and the density of states, $D(E_F)$ (extracted from the measured Pauli susceptibility $\chi^p$ exhibit the same dome shaped behavior as a function of electron density. Optimally intercalated samples have an upper critical field \approx 4 T and $\Delta/k_BT_c$ \approx 2.7. Accompanying the development of superconductivity, the films show a reversible electrochromic change from transparent to colored and are partially transparent (orange) at the peak of the superconducting dome. This reversible intercalation of alkali and alkali earth ions into thin ITO films opens new opportunities for tunable superconductivity.
