  Reaching a high precision of the top quark mass is an important task of the
Large Hadron Collider. We perform a feasibility study of measuring the top
quark mass through the three-point energy correlator. The expected sensitivity
of the top quark mass in the boosted regime is presented. We further introduce
its application to the low top $p_\text{T}$ regime and demonstrate that both
the W boson and the top quark masses could be extracted from this single
observable. Compared to traditional observables, the energy correlator shows
robustness to uncertainties that usually dominate experimental measurements and
provides a promising way to improve experimental precision.
