We identify and analyze the host galaxy of the fast radio burst FRB191001, in order to constrain possible progenitors for this burst. We identify the host with P=0.0034 that the galaxy is unrelated to the burst and then find that FRB191001 has an offset of roughly ∼12kpc from the center of the galaxy. We measure the line fluxes of Hα, Hβ, OII and NII in order to obtain key pieces of information about the galaxy. The host galaxy has a redshift of z=0.235, stellar mass of 4:6±1:910M , a star formation-rate of 3:4M yr−1 and oxygen abundance 12+log(O/H) = 8.8. We then use these values to compare with other transients, eventually ruling out that the progenitor is an active galactic nucleus and finding little likelihood that the host galaxy would also host a long gamma-ray burst. However the galaxy may also host short gamma-ray bursts, SNe Ia or core-collapse supernovae
