"So Beautiful" is a song written by Australian singer-songwriter Darren Hayes and Robert Conley.

In 2005, the song was released as a single as a part of the promotion of the greatest hits album Truly Madly Completely: The Best of Savage Garden, a band that Hayes was part of until their split in 2001.

The song was written for Hayes's boyfriend Richard Cullen, whom he married in a civil partnership ceremony in London on 19 June 2006.

The song peaked at number 27 on the US Adult Contemporary chart.

The single version of the song contains a different introduction and a slightly faster tempo.
