  We demonstrate that gluon transverse-momentum-dependent parton distribution
functions (TMDPDFs) can be extracted from lattice calculations of appropriate
Euclidean correlations in large-momentum effective theory (LaMET). Based on
perturbative calculations of gluon unpolarized and helicity TMDPDFs, we present
a matching formula connecting them and their LaMET counterparts, where the
latter are renormalized in a scheme facilitating lattice calculations and
converted to the $\overline{\rm MS}$ scheme. The hard matching kernel is given
up to one-loop level. We also show that the perturbative result is independent
of the prescription used for the pinch-pole singularity in the relevant
correlations. Our results offer a guidance for the extraction of gluon TMDPDFs
from lattice simulations, and have the potential to greatly facilitate
perturbative calculations of the hard matching kernel.
