We report the observation of the de Haas--van Alphen effect in ${\mathrm{IrTe}}_{2}$ measured using torque magnetometry at low temperatures down to 0.4 K and in high magnetic fields up to 33 T. ${\mathrm{IrTe}}_{2}$ undergoes a major structural transition around $\ensuremath{\sim}283(1)\phantom{\rule{0.28em}{0ex}}\mathrm{K}$ due to the formation of planes of Ir and Te …
