It has signed a deal with Australian finance firm AMP - which already has a naming rights deal in place with Surrey's home ground, the AMP Oval.
"We are now one year into our five-year term at the AMP Oval and are delighted at the way our partnership has developed," said Tom Fraser, managing director of AMP's UK financial services.
"This further marketing partnership reinforces our commitment both to cricket as a sport and Surrey County Cricket Club as a team and offers a great opportunity to further raise the profile of the AMP brand in the UK."
