Axion emission from SN1987A by nucleon-nucleon axion bremsstrahlung is considered. On the basis of the neutrino observations the axion luminosity must be 10^53 erg s^-1. This occurs if (1) axions couple very weakly: m₀0. 7510^-3 eV; or (2) axions couple strongly enough to be ``trapped'' and radiated from an ``axion sphere'' with T₀8 MeV: m₀2. 2 eV. In general, ``axion trapping'' occurs for m₀0. 016 eV. Our mass constraints are at best reliable to within a factor of 3.
