An annual phone-in poll (more recently also open to Internet voting) of the listeners of the Australian youth radio station Triple J, to determine their favourite song of the year. Voting begins with the new year for the previous year's song, The 100 most popular songs are then counted down on Australia Day, January 26.

The poll regularly attracts about 200,000 voters.

A compilation CD featuring about 35 of the songs in the countdown is released a few months after the count - it is massively popular and a huge moneyspinner for the station - to give some idea of their popularity the first CD is still available nine years after its release in 1993.
