The 31-year-old, who had reportedly courted interest from St Johnstone, has penned an 18-month contract Victoria Park.
"He's not had the starts he wanted this season at Hibernian and he'll be a good signing for us," County manager Derek Adams told BBC Sport.
Adams also revealed that he is close to signing two more players, but added that he could not reveal their names "until the paperwork is finalised".
