  We introduce a prescription to compute the entanglement entropy of Galilean
conformal field theories by combining gravitational anomalies and an
\.{I}n\"{o}n\"{u}-Wigner contraction. We find that our expression for the
entanglement entropy in the thermal limit reproduces the Cardy formula for
Galilean conformal field theories. Using this proposal, we calculate the
entanglement entropy for a class of Galilean conformal field theories, which
are believed to be dual to three-dimensional flat-space cosmological solutions.
These geometries describe expanding (contracting) universes and can be viewed
as the flat-space limit of rotating Ba\~nados-Teitelboim-Zanelli black holes.
We show that our finding reduces, in the appropriate limits, to the results
discussed in the literature and provide interpretations for the previously
unexplored regimes, such as flat-space chiral gravity.
