Chamaraja Wodeyar IV (25 July 1507 – 9 November 1576) was the seventh maharaja of the Kingdom of Mysore.
Although Timmaraja Wodeyar II had declared Mysore Kingdom independent of the Vijayanagara Empire, it was not ratified.
He immediately expelled the Vijayanagar envoys and revenue collectors from Mysore Kingdom.
Kempe Gowda I built a town out of an uninhabited mass of land around the time Chamaraja Wodeyar IV was born.
Chamaraja Wodeyar IV led an expedition after Kempe Gowda's death in 1569 and acquired Bangalore.
