if you mean air like the one earth has, no, the moon has no air but it has a relatively insignificant and tenuous atmosphere. One source of this atmosphere is outgassing — the release of gases such as radon that originate by radioactive decay processes within the crust and mantle. Another important source is generated through the process of sputtering, which involves the bombardment of micrometeorites, solar wind ions, electrons, and sunlight.[15] Gasses that are released by sputtering can either reimplant into the regolith as a cause of the Moon's gravity, or can be lost to space either by solar radiation pressure or by being swept away by the solar wind magnetic field (if they are ionized). The elements sodium (Na) and potassium (K) have been detected using earth-based spectroscopic methods, whereas the element radon has been inferred from data obtained from the Lunar Prospector alpha particle spectrometer.[2 from this link; http://www.wikipedia.org greetings. : )
