V883 Orionis is a protostar in the constellation of Orion. It is associated with IC 430 (Haro 13A), a peculiar Hα object surveyed by Guillermo Haro in 1952.^[4] It is assumed to be a member of the Orion Nebula cluster at 414±7 pc.^[2]

V883 Orionis, like most protostars, is surrounded by a circumstellar disc of dust. The dust has a water snow-line, a certain distance where the stellar irradiance from the star is low enough that water can freeze to snow. The water snow-line was directly imaged by ALMA, when a stellar outburst increased the amount of insolation and pushed the line out farther.^[2] In 2023, it was announced that signs of water vapor had been detected in V883 Orionis' disc.^[5]
