Gloucestershire fast bowling coach Stuart Barnes has left Bristol to join Surrey.
Barnes will replace Martin Bicknell who will become the Oval club's chief scout.
Barnes, 42, had spent 15 years as a coach at Bristol, and will link up at the Oval with Jon Lewis, the former Gloucestershire captain who is now Surrey's opening bowler.
Surrey Team director Chris Adams said: "Stuart is a fantastic appointment for the club and is regarded as one of the finest bowling coaches in the country.
"He will be a very positive addition to both the coaching team and the dressing room."
Barnes added: "I've thoroughly enjoyed working as fast bowling coach for Gloucestershire in the last few years.
"I have really enjoyed coming into work every day and finding ways to make a positive difference to the coaching team and the playing staff.
"The amount of fast bowling talent at Surrey has been a massive attraction for me.
"Looking at the variety of talent I'm going to have available to me, we've got all our bases covered and I am looking forward to having a positive effect on every single one of them."
Surrey have a fearsome array of fast bowling talent at their disposal - as well as Lewis, they have England men Chris Tremlett, Stuart Meaker and Jade Dernbach plus the highly-rated Tim Linley and Chris Jordan.
