The Brazil international has been rewarded for his importance to Hansi Flick's side, having emerged as one of the team's leading figures since arriving from Leeds United in 2022.
Barcelona confirmed the extension on Thursday, November 5, with the 29-year-old signing the agreement in the presence of club president Joan Laporta.
Raphinha's previous contract was due to run until 2028, but the new deal will keep him at the club for a further two seasons beyond that date.
The extension comes after a remarkable opening to the 2026-27 campaign. Barcelona say Raphinha has scored 19 goals in 13 appearances across LaLiga and the Champions League, including 15 in the league and four in Europe.
His latest performances have reinforced his status as one of the most influential players in Flick's squad, while the club have also secured the future of a player who attracted interest from Saudi Arabia last summer.
Raphinha joined Barcelona from Leeds for a reported €58 million in 2022 and has since become a key part of the team's attacking structure.
He has now scored 94 goals in 190 appearances for the Catalan club, making him the fourth-highest scoring Brazilian in Barcelona's history and fourth in appearances among players from his country.
The extension is a significant piece of business for Barcelona, who have moved to secure one of their most important players while he is enjoying arguably the finest form of his career.
Raphinha's new contract runs until June 30, 2030, ensuring that the Brazilian will remain a central figure in the club's plans for the foreseeable future.
