Nathan William Hindmarsh (born 7 September 1979) is an Australian former professional rugby league footballer who captained the Parramatta Eels in the NRL.

A New South Wales State of Origin and Australian international representative second-row forward, he played his entire career at the Eels, in 2010 breaking the record for most games with the club.

[7] In 2001, Hindmarsh was part of the all conquering Parramatta side which only lost 4 games all season on their way to the Minor Premiership and then the 2001 NRL Grand Final against Newcastle.

On breaking Brett Kenny's record for most appearances, Hindmarsh recalled memories of the 2001 final saying "I was jogging back to the half way line crying after Timana Tahu scored that try to make it 28-6 with 16 minutes to go because I knew we were gone".

[11] Hindmarsh was selected to play for the Australian national team at second-row forward in the 2007 ANZAC Test match against New Zealand, scoring a try in the Kangaroos' 30–6 victory.

After a courageous performance in the 2009 NRL Grand Final, Nathan Hindmarsh earned a well-deserved Test recall after two years of being overlooked for representative honours.

In 2010 when it was revealed that Melbourne had been found guilty of rorting the salary cap, there was a possibility that Parramatta could be given the 2009 premiership or that the 2009 season could be left vacant.

On 2 September 2012, Hindmarsh played his final NRL game alongside retiring winger Luke Burt against the St. George Illawarra Dragons.
