The 2009 Indian Premier League season, abbreviated as IPL 2 or the 2009 IPL, was the second season of the Indian Premier League, established by the Board of Control for Cricket in India (BCCI) in 2007. The tournament was hosted by South Africa and was played between 18 April and 24 May 2009. It was the second biggest cricket tournament in the world, after the Cricket World Cup, and was forecast to have an estimated television audience of more than 200 million people in India alone.

The Indian Premier League (IPL), also known as the TATA IPL for sponsorship reasons, is a men's Twenty20 (T20) cricket league held annually in India. Founded by the BCCI in 2007, the league features ten city-based franchise teams. The IPL usually takes place during the summer, between March and May each year. It has an exclusive window in the ICC Future Tours Programme, resulting in fewer international cricket tours occurring during the IPL seasons.
