João Pedro da Silva Pereira (born 25 February 1984 in Lisbon) is a Portuguese footballer who plays for Valencia CF in Spain and the Portuguese national team, mainly as a right defender.

Benfica
A product of S.L. Benfica's youth system, Pereira first appeared with its main side on 17 August 2003 in a 0–0 away draw against Boavista FC, and finished his debut season with 25 league appearances, mostly as a midfielder.

He was part of the Benfica squad that won the 2005 championship, starting often, until a fallout with coach Ronald Koeman relegated him to the bench, and later to the B team. He was sold to Gil Vicente F.C. in the 2006 summer, after a previous loan to the same team – also in the top flight.

Braga
In 2007–08, fully reconverted into a right back, Pereira joined S.C. Braga, as another player in the position, Luís Filipe, went the other way.

An undisputed starter from the beginning, he scored his first goal for the Minho side on 22 February 2009, a 2–1 last-minute winner at Associação Naval 1º de Maio; he also collected 18 yellow cards and one red in his first two seasons combined.

Sporting
On 22 December 2009, Pereira moved to Sporting Clube de Portugal for a fee of €3 million; at the time, Braga led the league alongside Benfica, with 12 points in advance to his new club, with the Lions eventually finishing fourth.

Pereira again featured regularly for Sporting in the 2010–11 season, both as a defender and a midfielder, as his team ranked in third position. On 30 April 2011, he scored in a 2–1 home win against Portimonense SC, but was also sent off midway through the second half (after teammate André Santos) for repeatedly and severely insulting referee Duarte Gomes.

Valencia
On 24 May 2012, Pereira signed with Valencia CF in Spain for €3.6 million, penning a 3+1 contract. He made his official debut on 19 August, playing the full 90 minutes in a 1–1 away draw against Real Madrid.
