Peter Alexander Stringer (born 13 December 1977) is an Irish former rugby union player who played at scrum-half.

[7][8] Stringer played a key role for Munster during the 2005–06 Heineken Cup, helping the team reach their third final.

[11] During the 2010–11 season, Stringer also became Munster's most capped player ever, overtaking the record previously held by Alan Quinlan.

[21] Stringer agreed an extension to his loan deal with Bath in March 2013, which saw him stay with the side until the end of the 2012–13 season.

[22] It was announced on 9 April 2013 that Stringer had signed a one-year contract with Bath, which saw him join the club as a full-time player from the 2013–14 season.

[29] On 20 July 2017, Worcester Warriors announced that they had signed Stringer on a six-month contract to cover Francois Hougaard while he is on international duty.

The contract meant Stringer would be playing professional rugby as a 40-year-old and would join his longtime Munster and Ireland teammate Donncha O'Callaghan at the club.

Stringer quickly became known for his ability to take down larger players, especially with one handed "Ankle taps" [3], and game changing moments.

[35] Stringer, having lost his starting role to Eoin Reddan, played in three of Ireland's five matches in the 2008 Six Nations coming off the bench as a substitute in each one.

Losing 12–9 at half-time in Murrayfield, Stringer made a break and passed to Jamie Heaslip, who scored a match-turning try that eventually saw Ireland win 15–22.

In the dying minutes of the game, Stringer passed the ball from a ruck to Ronan O'Gara, who then scored the drop-goal that won Ireland's first Grand Slam since 1948.

[39] He was also in the 2007 Rugby World Cup squad,[40] but played only in the first two pool games, before being replaced by Eoin Reddan took over the starting scrum-half role for Ireland for the remainder of the tournament.
