The classical nova, AT 2023prq, was discovered on 2023 August 15 and is located at a distance of 46 kpc from the Andromeda galaxy (M31). Here we report photometry and spectroscopy of the nova. The "very fast" (days) and low luminosity () nature of the transient along with the helium in its spectra would indicate that AT 2023prq is a "faint-and-fast" He/N nova. Additionally, at such a large distance from the center of M31, AT 2023prq is a member of the halo nova population.
