Piri Awahou Tihou Weepu (born 7 September 1983) is a retired New Zealand rugby union player.

In 2005 was called back into the All Blacks squad for the first Tri Nations test against South Africa, having missed selection for the 2005 British & Irish Lions tour.

[5] After leaving school he played senior rugby with Hutt Old Boys Marist, under the tutelage of his mentor Derek Bruce, but returned to his roots and later joined Wainuiomata RFC with whom he remained affiliated throughout his professional career.

[7] Weepu was not selected for the 2007 Rugby World Cup squad, announced on 22 July 2007, with Crusaders halfback Andrew Ellis preferred.

This time round it looked to be New Zealand's year, but All Blacks playmaker Dan Carter was struck with a season-ending groin injury.

Landing seven penalties, with only a missed conversion, Weepu was named Man of the Match, helping guide New Zealand to victory, as well as earning him the nicknames "Mr Fixit" and "saviour".

[8] Weepu was left out of the All Blacks squad for the June tests in 2013, being told he needed to work on his speed and defensive ability.

Of the 71 tests he played in he was the haka leader in 51 of them (12 November 2005 – 22 June 2013); this is the most for any player since the introduction of Kapa o Pango in 2005 (tied with TJ Perenara for 51 in total).

Weepu signed to join London Welsh in July 2014 and left the Auckland Blues at the end of the 2014 Super Rugby season.

[9][10] On 27 February 2015, it was announced Weepu had been released early from London Welsh and would join fellow Aviva Premiership side Wasps on a short-term deal until the end of the 2014–15 season.

[17] He revealed in 2020 that he still resides in Wainuiomata, Lower Hutt, and that he suffered a stroke in 2014 while playing for London Welsh, where scans found blood clots in his Broca's area, which made him talk nonsensically like a baby for a while.
