Surrey captain Adam Hollioake will quit cricket at the end of the 2004 season.
Hollioake has represented the county for 14 years and has been captain for the final seven of those.
He said: "After much soul searching I have decided that 2004 will be my final year.
"I have many things that I want to do with my family, charity work with the Ben Hollioake Fund and my business interests in Perth.
"I will continue to give everything I can to the club in the next 12 months, and in the years to come."
Chief executive Paul Sheldon added: "We have had many discussions with Adam about his future, which have been open and honest throughout.
"Of course, we are very sad that Adam will be retiring at the end of next season, as he has been an outstanding captain and the most pivotal character in the club's success of recent years.
"We will continue to plan for Adam's succession and will ensure a smooth handover in to a new era."
