Tsonga reached the final of the Australian Open in 2008
Frenchman Jo-Wilfried Tsonga is among the big names entered for next month's pre-Wimbledon AEGON International tournament in Eastbourne.
Last year's winner Michael Llodra and Serbian Janko Tipsarevic have also entered the popular Devonshire Park event, which runs from 12-18 June.
Tsonga said: "I'm really looking forward to playing on the grass courts.
"I am sure there'll be a good atmosphere and I'm hoping to get some wins under my belt ahead of Wimbledon."
Australian Lleyton Hewitt, who lifted the Wimbledon title in 2002, has also announced he will play in Eastbourne.
Tournament director Gavin Fletcher added: "It's fantastic to see Lleyton and Jo-Wilfried both enter Eastbourne.
"To see 11 of the world's top fifty players proves the men's line-up is getting stronger."
