Frog House (Polish: kamienica Pod Żabami) is an example of art nouveau architecture in the city of Bielsko-Biała, in southern Poland's Silesia Province. It features two frogs seated over the entrance, one smoking a pipe and the other playing a mandolin, while beetles roam freely over the walls.
The Frog House stands on Bielsko-Biała's Polish Army Square (plac Wojska Polskiego).
