No: Vapor is defined as the gas phase of a substance that is mostly solid or liquid at equilibrium at standard temperature and pressure. Therefore, a liquid itself is never a vapor, but the liquid is in equilibrium with a vapor phase that contains the same chemical substance.

In a system at constant vapor pressure, a dynamic equilibrium exists between the vapor and the liquid. The system is in equilibrium because the rate of evaporation of liquid equals the rate of condensation of vapor.
