Supermassive stars, with masses exceeding 10,000 times the mass of the Sun, are predicted to form within a small fraction of primordial protogalaxies at redshifts z > 10. As these objects would collapse to form similarly massive black holes, they are promising candidates for the seeds of supermassive black holes, some of which are inferred to have grown to a billion solar masses by z 7. Here we consider the processes that set the maximum mass that such stars can attain by the accretion of primordial gas. We find that the strong ionizing radiation emitted from massive primordial stars can eventually shut off their growth at relatively low accretion rates. However, the upper mass limit for supermassive stars is set by their main sequence lifetime, which becomes very short at high accretion rates.
