The 2024 Rio Grande do Sul floods were severe floods caused by heavy rains and storms that hit the Brazilian state of Rio Grande do Sul, and the adjacent Uruguayan cities of Treinta y Tres, Paysandú, Cerro Largo, and Salto. From 29 April through to May, it resulted in 181 fatalities (as of 7 July 2024), widespread landslides, and a dam collapse. It is considered the country's worst flooding in over 80 years.

The floods marked the fourth such environmental disaster in Brazil within the past 12 months, following similar calamities that killed 75 people in July, September, and November 2023.
