AB Path-integral Monte Carlo simulations have been used to determine the phase diagram of a two-dimensional 4He film in a range of temperatures and coverages where it undergoes solidification, superfluidity, and a liquid-gas transition (0.25K<~T<~1.5K¿0<¿<0.094¿Å-2). We determine the phase-transition densities and give the coefficients for a functional form of the free energy in the liquid, solid, and gas phases. The phase diagram is similar to the one determined from experimental measurements of a second layer of helium on graphite.
