Abstract: 
The quantum predictions for a single nonrelativistic spin-1/2 particle can be reproduced by noncontextual
hidden variables. Here we show that quantum contextuality for a relativistic electron moving in a Coulomb
potential naturally emerges if relativistic effects are taken into account. The contextuality can be identified
through the violation of noncontextuality inequalities. We also discuss quantum contextuality for the free Dirac
electron as well as the relativistic Dirac oscillator.
