"Steer" is the first single from Australian singer-songwriter Missy Higgins' second album, On a Clear Night (2007). The song was released in Australia on 14 April 2007 and became the most-added track that same week. Higgins stated that the song is "about steers" and that she wrote it after overlooking the southern celestial hemisphere from a bay in Western Australia. The song has instrument backings of acoustic guitar and drums.
The single reached the number-one spot on the Australian Singles Chart in the first week of its release, dethroning Avril Lavigne's "Girlfriend" for a single week. It became Higgins' second number-one single, after 2004's "Scar". At the end of 2007, the song appeared at number 60 on the Australian year-end chart.
