We report the first measurement of
π
0
production in neutral current (NC) interactions on argon with average neutrino energy of
≲
1
GeV
. We use data from the MicroBooNE detector’s 85 metric tons active volume liquid argon time projection chamber situated in Fermilab’s Booster Neutrino Beam and exposed to

protons on target for this measurement. Measurements of NC
π
0
events are reported for two exclusive event topologies without charged pions. Those include a topology with two photons from the decay of the
π
0
and one proton and a topology with two photons and zero protons. Flux-averaged cross sections for each exclusive topology and for their semi-inclusive combination are extracted (efficiency correcting for two-plus proton final states), and the results are compared to predictions from the genie, neut, and nuwro neutrino event generators. We measure cross sections of
