We determine three independent Population II distance moduli to the Fornax dwarf spheroidal (dSph) galaxy, using wide-field, ground-based VI imaging acquired with the Magellan-Baade telescope at Las Campanas Observatory. After subtracting foreground stars using Gaia EDR3 proper motions, we measure an I-band tip of the red giant branch (TRGB) magnitude of I_0_^TRGB^=16.753+/-0.03_stat_+/-0.037_sys_mag, with a calibration based in the LMC giving a distance modulus of {mu}_0_^TRGB^=20.80+/-0.037_stat_+/-0.057_sys_mag. We determine an RR Lyrae (RRL) distance from template mean magnitudes, with periods adopted from the literature. Adopting a Gaia DR2 calibration of first overtone RRL period-luminosity and period-Wesenheit relations, we find {mu}_0_^PLZ^=20.74+/-0.01_stat_+/-0.12_sys_mag and {mu}_0_^PWZ^=20.68+/-0.02_stat_+/-0.07_sys_mag. Finally, we determine a distance from Fornax's horizontal branch (HB) and two galactic globular cluster calibrators, giving {mu}_0_^HB^=20.83+/-0.03_stat_+/-0.09_sys_mag. These distances are each derived from homogeneous IMACS photometry, are anchored to independent geometric zero-points, and utilize different classes of stars. We therefore average over independent uncertainties and report the combined distance modulus <{mu}_0_>=20.770+/-0.042_stat_+/-0.024_sys_mag (corresponding to a distance of 143+/-3kpc).
