Willem "Wim" Drees Jr. (24 December 1922 – 5 September 1998) was a Dutch politician of the Democratic Socialists '70 (DS'70) party and economist.

Drees worked as a civil servant for the Ministry of Colonial Affairs in Batavia, Dutch East Indies from 1945 until 1947 and as a financial analyst at the International Monetary Fund (IMF) from 1947 until 1950.

In December 1970 Drees was approached by Jan van Stuijvenberg, the chairman of the newly founded Democratic Socialists '70 (DS'70), to seek the leadership for the 1971 general election.

The cabinet fell just one year later on 19 July 1972 after DS'70 retracted its support following their dissatisfaction with the proposed budget memorandum to further reduce the deficit.

Drees returned to the House of Representatives and resumed his position as his party's parliamentary leader, taking office on 5 September 1972.

After attending Gymnasium Haganum from 1934 to 1940, Drees studied at the Erasmus University Rotterdam from 1940 to 1946, and gained his doctorate there in 1955.
