Measurements of the Higgs Boson Coupling Properties to Fermions with the ATLAS Detector

Testing the Yukawa couplings of the Higgs boson to quarks and leptons is important to understand the origin of fermion masses. These proceedings will review several measurements of Higgs boson decays to two bottom quarks or two tau leptons, searches for Higgs boson decays to two charm quarks or two muons, as well as direct constraints on the charm-Yukawa coupling. The production of Higgs boson in association with top quarks will also be discussed. These analyses are based on 139 fb${}^{-1}$ of Run-2 data from proton-proton collisions collected by the ATLAS experiment at the Large Hadron Collider (LHC) with a center-of-mass energy of 13 TeV.
