The 1966 Hobart Carnival was the 16th edition of the Australian National Football Carnival, an Australian rules football interstate competition. It was the final time that Tasmania hosted a carnival. It was competed by two Victorian sides, one from the Victorian Football League (VFL) and another from the Victorian Football Association (VFA), as well as South Australia, Western Australia and the home state Tasmania. The VFL topped the ladder as the only undefeated team and Peter Hudson was the leading goal-kicker with 20 goals.
