Lasowice Wielkie [lasɔˈvit͡sɛ ˈvjɛlkʲɛ] is a village in Kluczbork County, Opole Voivodeship, in south-western Poland.

In the Upper Silesia plebiscite of 20 March 1921, 394 inhabitants (84.2%) voted to remain in Germany, 74 for Poland.

Thus Groß Lassowitz remained part of the Weimar Republic.

The village is officially bilingual as the majority of its population are Germans.
