Former England star Bell has committed to the club for next summer in a deal which takes his time in the Warwickshire senior ranks to 23 years.
Five-time Ashes winner Bell, 38, who first joined the Warwickshire set-up as a 10-year-old, made his First Class debut in 1999 and became a fixed part of the senior team in 2001, winning his county cap later that year.
“It means a huge amount to me, and my family, that I am able to continue representing my home county,” said Bell. “I still harbour big ambitions of winning more silverware and I know Paul Farbrace and the rest of the squad share this determination and excitement.
“I’ve been fortunate to be part of some fantastic Warwickshire sides that have won trophies across formats throughout my time with the club, and I firmly believe that we are building for another period of challenging for more titles.
“In the last couple of years we’ve seen some really promising young players come into the side and make an immediate impression. Part of my role now is to provide support to them as they have the potential to achieve a huge amount both with Warwickshire and England.
“I believe that it’s a very exciting time for the club and I can’t wait to get back out there wearing the Bear & Ragged Staff.”
