Adolf Marcus "Dolf" Joekes (5 May 1884 – 1 April 1962) was a Dutch politician and diplomat of the Free-thinking Democratic League (VDB) and later co-founder of the Labour Party (PvdA) and businessman.

After the 1933 general election the parliamentary leader of the Free-thinking Democratic League in the House of Representatives Henri Marchant was appointed as Minister of Education, Arts and Sciences in the Colijn II cabinet and selected Joekes as his successor, taking office on 1 June 1933.

Following the 1937 general election, Pieter Oud returned to the House of Representatives but asked Joekes to remain as parliamentary leader until 20 September 1937.

In October 1938 Pieter Oud was nominated as Mayor of Rotterdam and he announced he was stepping down as parliamentary leader and endorsed Joekes as his successor.

Following the end of World War II, Queen Wilhelmina ordered a Recall of Parliament and Joekes remained in the House of Representatives.
