Brown, 32, who has played for both Rangers and Celtic in the past, joined County last summer.
Manager Derek Adams told the club's website: "The club and Mark have agreed to extend his contract. Mark is recovering well from injury and will be able to start pre season training with the rest of the squad on Thursday the 27th of June."
County finished last season fifth in the SPL.
