Beauty quark production in ep collisions is being studied at HERA. The latest results in deep inelastic scattering (DIS) and photoproduction (PHP) regime performed by the ZEUS and HI experiments are presented here. The first measurement exploits the potential of the ZEUS mi-crovertex detector to identify beauty in PHP dijet events in an inclusive analysis. In the second measurement, beauty quarks were identified through their decays into muons. Finally, two measurements of the beauty contribution to the proton structure function, F{sub 2}{sup b???b}, in DIS are presented. The four measurements are consistent with previous results and are reasonably well described by QCD predictions.
