The Łódź Ghetto coinage is currently listed under Poland/General Government Emergency coinage, but it was only for the ghetto.
I can't find an ghettos under Issuers, just cities, towns, municipalities, but I also can't find other coinage listed in Numista for another ghetto.
English name: Łódź Ghetto (Ghetto Litzmannstadt)
French name: ghetto de Łódź
Spanish name: gueto de Łódź
(The Litzmannstadt version is listed in Wikidata under English, German, and some other languages but not under French or Spanish.)
