José Paolo Guerrero González (Spanish pronunciation: [xoˈse paˈolo ɣeˈreɾo ɣonˈsales]; born 1 January 1984) is a Peruvian professional footballer who plays as a striker for Peruvian Primera División club Alianza Lima and the Peru national team. Known as one of the best Peruvian and South American strikers of his time, he was key to Peru's successes in the 2000s through 2010s, giving him the nickname, el Depredador (the Predator).

"A legend in South American football" for the New York Times, he has been Peru's most important football player for two decades. Forging his career in Germany, Guerrero started at giants Bayern Munich, before making his name at Hamburger SV, scoring 47 goals across eight Bundesliga seasons. His greatest successes came in Brazil, where he scored the winning goal of the 2012 FIFA Club World Cup final for Corinthians.

With 40 goals in 128 matches for Peru since debuting at 20, Guerrero holds the honour of being the highest goalscorer for his national team. He has represented them at six Copas América and one World Cup. He led them to third place in the 2011 and 2015 Copas, and to runners-up in 2019, finishing as top scorer in all three of these tournaments. He is also the top scoring active player in the Copa América. He was one of 59 nominees for the 2015 FIFA Ballon d'Or, becoming the first Peruvian to receive that recognition. He's also the oldest Peruvian player to appear in a World Cup, at the age of 34 years and 177 days.

In 2021, the IFFHS included Guerrero in their best South American team of the last decade, being recognized as the best South American center forward between 2010 and 2020 (joining the podium with Neymar and Sergio Agüero). In addition, he was voted the "best centre forward in America" in 2012 and 2017 by the newspaper El País, based on the opinion of some two hundred journalists from the region. He has also been named included by CONMEBOL in the teams of the tournament for the 2011, 2015 and 2019 Copas América.

Guerrero was born in Lima, starting his football career in the youth teams of Alianza Lima. In 2003, he signed a contract with Bavarian giants Bayern Munich. During the 2003–04 season, Guerrero played in the Regionalliga Süd where he scored 21 goals in 23 games. During the 2004–05 season, he joined fellow countryman Claudio Pizarro as a member of the Bayern first team.

At the beginning of 2002, after rejecting an offer from K.R.C. Genk of Belgium, Bayern Munich of Germany announced his incorporation to the second team. This signing led to a conflict between Alianza Lima and Bayern. The case was raised to FIFA, which decided that the German club should pay for training rights since, although Guerrero had a formal contract with Alianza, it was not of a professional nature. Once the problem was solved, Guerrero began playing with Bayern Munich II in the Regionalliga South, which at that time was the third division of German football. On May 30, 2004 he was crowned champion in this category.

At the team level, he played his first game with the Bayern professional team on October 23, 2004 against Hansa Rostock.with the number "33", while his first goal in the Bundesliga was scored against Hannover 96. In total, Guerrero spent four seasons at Bayern Munich, alternating the last two in the first team, the same team with which he scored ten goals in the Bundesliga and two in the UEFA Champions League.

In June 2006 he left Bayern Munich. His destination was Hamburger SV, a club with which he signed a four-year contract.
