1934 flood in Poland was the biggest flood in the Second Polish Republic. It began with heavy rains in the Dunajec river basin, which took place between 13 and 17 July 1934. In the following days, the flood spread to the basins of the Raba, Wisłoka, and Skawa, all of which are tributaries to the Vistula. The disaster took the lives of 55 people and caused damages estimated at 60 million interbellum Polish zlotys.
