Carrer Princesa, Historic street in Sant Pere district, Barcelona, Spain.

Carrer de la Princesa runs straight from Via Laietana to Passeig de Picasso, forming with Carrer de Ferran and Carrer de Jaume I a single axis opened toward La Rambla. It crosses the Sant Pere, Santa Caterina i la Ribera sector and is often taken as the boundary between Santa Caterina and La Ribera. Most buildings date from 1853 to 1870 and keep a uniform academic-romantic frontage; the far section, the Porxos d'en Fontserè, has three-storey blocks with arcaded ground floors designed by Josep Fontserè.

The street received its official opening on November 19, 1853, marking an important phase in Barcelona's urban expansion during the 1800s. This development helped reorganize the densely settled neighborhood with new pathways and modern structures for that era.

Carrer Princesa displays traditional Catalan building forms that shape the street's character and identity. The protected facades show how local architecture has housed residents and businesses across many generations.

The street offers restaurants, cafes, and shops on both sides, making it easy to walk and stop at various places. Parking in the surrounding area is limited, so visiting on foot or by public transport is most practical.

The street appears in Barcelona's festive imagery as the Gegants del carrer de la Princesa, the giant figures that represent it during the city's popular celebrations. The street also marks the modern boundary between the Santa Caterina and La Ribera neighbourhoods.
