Dato' Seri Anwar bin Ibrahim (born 10 August 1947) is a Malaysian politician who served as Malaysian Deputy Prime Minister from 1993 to 1998. Early in his career, he became a protégé of the Prime Minister Mahathir bin Mohamad, but subsequently emerged as the most prominent critic of Mahathir's administration.

In 1999, he was sentenced to six years in prison for corruption, and in 2000, to another nine years for sodomy. In 2004, the Federal Court reversed the second conviction and he was released. In July 2008, he was arrested over allegations he sodomised a male aide.

On 26 August 2008, Anwar won the Permatang Pauh by-election with a majority of 15,671, returning to Parliament as leader of the Malaysian opposition. He currently faces new sodomy charges in the Malaysian courts.
