| Résume | Measure equivalence is an equivalence relation on the space of groups that was defined by Gromov in the 90's as an analytic analogue of quasi-isometry. Let F be a nonabelian free group. We show that if $L_1$ and $L_2$ are measure equivalent groups, then the wreath products $L_1\wr F$ and $L_2\wr F$ are measure equivalent with index 1. This is joint work with Robin Tucker-Drob.
