Stephen Rex Donald (born 3 December 1983) is a New Zealand rugby union player who currently plays for the NEC Green Rockets in the Japanese Top League.

He played First five-eighth for the Wesley First XV rugby team, coached by Nick Leger, along with Sitiveni Sivivatu, Tame Tupou, Viliame Veikoso, Sailosi Tagicakibau, Ezra Taylor and Tomasi Soqeta.

[4] The Blues denied reports stating that Donald had signed for the team for 2012 as a replacement for Stephen Brett and Luke McAlister, who are both heading overseas.

[5] In April 2013, it was announced Donald would leave Bath Rugby to join Japanese side Mitsubishi Sagamihara DynaBoars in the Top League for the 2013/14 season.

In the 60th minute of the game, Donald came on as a substitute for Dan Carter and the All Blacks held a five-point lead, just after Drew Mitchell scored a converted try.

During training the day before the All Blacks match against Canada, Dan Carter sustained a tournament-ending groin injury and was subsequently replaced by Aaron Cruden.

On 9 October, Colin Slade sustained a groin tear which led to Donald receiving a call-up as replacement first-five for the All Blacks heading into the finals.

Coupled with Tony Woodcock's try, Donald's penalty-kick was ultimately what won the New Zealand side their second Rugby World Cup.

[7][10] In honour of his contribution to winning the World Cup, his local rugby club in Waiuku has renamed their home ground to Beaver Park.

Test record overall:[12] Donald appeared alongside Israel Dagg and Hamish Dodd in the New Zealand 2023 television series, Clubhouse Rescue.
