Abdul Ghafar bin Baba (Jawi: عبدالغفار بن باب; 18 February 1925 – 23 April 2006) was a Malaysian politician who served as 6th Deputy Prime Minister of Malaysia from 1986 to 1993.

He was born on 18 February 1925 in Kuala Pilah, Negeri Sembilan, the son of impoverished villagers from Malacca state who emigrated as pastoral nomads, namely Baba Abdullah from Sungai Udang and his wife, Saodah Salleh from Bemban.

Ghafar Baba became a teacher and later became a member of the United Malays National Organisation (UMNO) political party, which is part of the Barisan Nasional coalition.

In the early 1990s, he polygamously married his second wife, Toh Puan Heryati Abdul Rahim, with whom he had one child, and divorced in 2003.

Previously, Musa Hitam held the deputy premiership but resigned, citing irreconcilable differences with Mahathir.
