  We present the analytical calculation of entanglement entropy for a class of
two dimensional field theories governed by the symmetries of the Galilean
conformal algebra, thus providing a rare example of such an exact computation.
These field theories are the putative holographic duals to theories of gravity
in three-dimensional asymptotically flat spacetimes. We provide a check of our
field theory answers by an analysis of geodesics. We also exploit the
Chern-Simons formulation of three-dimensional gravity and adapt recent
proposals of calculating entanglement entropy by Wilson lines in this context
to find an independent confirmation of our results from holography.
