Magnetic moments of single, double and triple heavy baryons containing charm or bottom quarks are calculated in a relativistic three-quark model, which in the heavy quark limit are consistent with Heavy Quark Effective Theory. The internal quark structure of baryons is modelled by using three-quark currents with quantum numbers of baryons constrained by QCD sum rules and covariant baryonic wave functions.
