Australia opener Ed Cowan will warm up for the Ashes with a stint at Nottinghamshire.
Cowan will play seven County Championship games for the Trent Bridge side as well as eight one-day fixtures.
The left-hander has become a fixture at the top of the Australia batting order over the last 12 months and made his best Test score of 136 in the recent series with South Africa.
"I was very keen to play some division one cricket and I'm pleased to have the opportunity to do that with Nottinghamshire," Cowan said.
"There are a lot of good players at the club and Trent Bridge is a great venue so I'm hoping to make a good contribution on and off the field."
Nottinghamshire's director of cricket Mike Newell added: "I feel very strongly we needed an opening batsman, and a left-hander is even more ideal.
"I met him last year and was impressed with the sort of bloke he was and his commitment to want to join a First Division team and play good quality cricket.
"Ed has an excellent record in Test cricket and there was an opportunity to sign him for a decent period.
"Our priority was to find a player who we felt could score a good volume of runs in four-day cricket, but Ed has a good one-day record as well and we're confident that he can make a difference."
