It will be Stan's eighth visit to Chennai and this year he will be looking to defend his title and claim a hat-trick.
The Swiss player has had a memorable season so far, highlighted with his triumph at the French Open.
The World No. 4 is the second player from Switzerland to win the Grand Slam on clay, joining his compatriot, and good friend, Roger Federer. He started the year with a title in Chennai and eighth ATP World Tour title overall.
Wawrinka said, "Chennai Open is a great way to start the season, and I look forward to my eighth year at the tournament. The last two years have been extra special since I have gone on to win a Grand Slam each year after a winning start here in Chennai. So, Chennai has become like my good luck charm now.
Ashu Jindal, Chief Operating Officer, IMG Reliance, said, "It is a pleasure and honour to welcome Stan Wawrinka for his eighth consecutive year. He is in great form with a win at the French Open and a great performance at the US Open this last fortnight. It is encouraging for us to see the continued participation from top players such as Stan and other international stars.
