Greatest Hits 1994–2004 is the second compilation album by Australian singer Tina Arena, released by Columbia Records in Australia on 25 October 2004.

It is a greatest hits album that contains all the singles released during her ten years signed with Columbia and also features two new songs.

Arena states that all the songs on the album are deeply personal and represent different periods and experiences of her life.

The album only produced one single, "Italian Love Song", which failed to make a major impact on the Australian ARIA Singles Chart just managing a peak within the top forty.

As a singer-songwriter, Arena felt she had worked "really hard to try to tell a story and hope that people identify with it in some way, whether they do when they listen to it for the first time or five years later.
