Measurements of the cross section for the reaction $p+p\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}+\mathrm{anything}$ have been completed. The data cover a range of incident proton energies 50-400 GeV, ${\ensuremath{\pi}}^{0}$ transverse momenta 0.3-4 GeV/c, and laboratory angles 30-275 mrad. The experiment was performed using the internal proton beam at the Fermi National Accelerator Laboratory. A lead-glass counter was used to detect photons from the decay of ${\ensuremath{\pi}}^{0}'\mathrm{s}$ produced by collisions in thin targets of hydrogen or carbon. Tables of the measured cross sections are presented.
