We extend this notion to arbitrary spacetimes. Given any gravitating region $a$, we define a max- and a min-entanglement wedge, $e_{\\rm max}(a)$ and $e_{\\rm min}(a)$, such that $e_{\\rm min}(a)\\supset e_{\\rm max}(a)\\supset a$.\n  Unlike their analogues in AdS/CFT, these two spacetime regions can differ already at the classical level, when the generalized entropy is approximated by the area.
