2010 State of Origin series

The 2010 State of Origin series was the 29th annual best-of-three series of interstate rugby league football matches between the Queensland and New South Wales representative teams played entirely under 'state of origin' selection rules. For the second year in a row, a Queensland victory set a new record for consecutive State of Origin titles, reaching five. Queensland won all three matches, completing their first series white-wash since 1995.

In a world first, the Nine Network broadcast free-to-air for the first match in 3D to the Sydney, Newcastle, Wollongong, Brisbane, Perth, Adelaide and Melbourne areas. Part-way through the series it became steeped in controversy, firstly for Israel Folau's announcement of his defection to the AFL and subsequent non-selection by Queensland, and secondly by New South Wales' Andrew Johns–Timana Tahu racial slur controversy. Queensland fullback Billy Slater was awarded the Wally Lewis Medal as Player of the Series.
