"All I Need Is You" is a single by Australian singer Guy Sebastian. The song was the second single released from Sebastian's debut album, Just as I Am (2003), following "Angels Brought Me Here". "All I Need Is You" reached number one on the Australian ARIA Singles Chart and was accredited platinum in Australia. The song also peaked at number five in New Zealand.
A music video was produced to promote the single. In the video, Sebastian is shown riding a bike through a rural landscape while couples show affection around him. Towards the end of the video, Sebastian is also shown in a crowded room with people dancing. During interviews conducted in early 2004, Sebastian stated that the video would show his first onscreen kiss; however, this was later found to be a joke.
