"Believe Again" is a New Age and electronica-influenced pop song written by Delta Goodrem, Brian McFadden, Stuart Crichton , Tommy Lee James and Nigel Hove produced by Stuart Crichton and Marius de Vries for Goodrem's third studio album Delta (2007). The single, released in Australia on 8 December 2007, features exclusive remixes and the unreleased B-side track, "Fortune and Love". The single was released to radio on 12 November 2007, although it had its premiere on commercial radio in late-October 2007.

The song was written by Goodrem, McFadden, Stuart Crichton and Tommy Lee James just after Christmas in 2006. On writing with fiancee McFadden, Goodrem said, "He is such a brilliant writer. I was intimidated by his talent, because we have really different writing styles." Goodrem states that the song brought about the focus the album needed when she stated, "The turning point came with the album's opening song 'Believe Again'. Before that I was feeling a little unsure about the direction of the new album. That song really turned things around for me in a lot of different ways."

The song has been noted to be about overcoming life's obstacles. Goodrem also stated that for her the song means a positive, uplifting shift in her writing style. Goodrem says about the song:

"The song closed the door to an era, after years of struggling. I actually stopped writing songs after recovering from cancer because I just needed to feel free from such artistic environment."

"Believe Again is about my constant perseverance. It shows that you can overcome anything in life as long as you have a strong belief in yourself", she explained.

During Delta's special A Night with Delta Goodrem, a fan asked the question "What song was your favourite to record off the new album, Delta?", with Delta replying "Believe Again".

Due to overwhelming demand for the remix used in Goodrem's AFI performance, the "Believe Again" Diamond Cut Remix was released on the "You Will Only Break My Heart" EP released on the Australian iTunes Store.

The video, shot in a warehouse in Sydney, was filmed in the week ending 20 October by Paul J Varolo (Producer) and Michael Spiccia (Director), a friend of Goodrem. In it, Goodrem plays different mystical characters including a water nymph most likely to be the Nymph of Springs Pegaeae, a crystal-covered, cave dwelling Wiccan or Nymph and a sky goddess swathed in navy satin, most likely Aušrinė, a Lithuanian sky deity.
