The Leniwa Obra ( German Faule Obra , Polish also Gniła Obra ) is a short, swampy river in western Poland .

It is a right tributary of the Obrzyca , but originally flowed directly into the Oder before it was regulated. The Leniwa Obra rises northwest of Brójce ( Brätz, municipality of Trzciel ), then flows in a southerly direction past Babimost (the former district town of Bomst ), flows through the Jezioro Wojnowskie and flows into the Obrzyca at Smolno Wielkie ( Groß Schmöllen, municipality of Kargowa ).
