Fresh from scoring 14 goals in 28 appearances to keep the club in the Bundesliga this season, the Peru marksman has put pen to paper on a new deal at Weserstadion.
Claudio Pizarro has signed a one-year contract extension with Werder Bremen.
The 37-year-old striker returned to the club for a third spell in September and scored 14 goals in 28 appearances to help it secure Bundesliga survival.
The Peru international, who leads Bremen's all-time scoring charts in the top flight on 103, is determined to fire the club to a better campaign in 2015-16 after the team escaped a relegation playoff on the final matchday this term with a 1-0 win over Eintracht Frankfurt.
