The northeastern section of Buenos Aires Province, Argentina, experienced several flash floods that killed at least 100 people.

Buenos Aires, officially the Buenos Aires Province, is the largest and most populous Argentine province. It takes its name from the city of Buenos Aires, the capital of the country, which used to be part of the province and the province's capital until it was federalized in 1880. Since then, in spite of bearing the same name, the province does not include Buenos Aires city, though it does include all other parts of the Greater Buenos Aires metropolitan region, which include approximately three-fourths of the conurbation's population. The capital of the province is the city of La Plata, founded in 1882.

Between 1 and 3 April 2013, the northeastern section of Buenos Aires Province, Argentina, experienced several flash floods that claimed the lives of 101 people. Greater La Plata was hardest hit with 91 reported deaths, and Greater Buenos Aires reported 10 deaths. The flooding was the result of extremely heavy rainfall and is said to be the worst flooding in La Plata's history.
