The new name, which is already reflected on the access signs, was a long-standing citizen demand that had been on the table for some time. Since 2022, it had been included in the list of modifications proposed by the Metropolitan Transport Authority (ATM) to better align station names with their geographical location.

The importance of this new nomenclature lies in the history of the population center of el Congrés i els Indians. The neighborhood is composed of apartment blocks built during the Franco regime to host the XXXV Eucharistic Congress of 1952, and the area known as Indians, built by those who had become wealthy in America and erected towers near the Passeig de Maragall.

According to the archives of Transports Metropolitans de Barcelona (TMB), the original plan for the station, inaugurated in 1959, envisioned the name Garcilaso, as it is located at the intersection with Puerto Principe street. This idea was discarded in favor of Viviendas del Congreso, promoted by the then bishop Gregorio Modrego.

The station began operating as part of the first section of Line II, transferring to L5 in 1970. In 1982, the name was Catalanized to Congrés. The latest change was celebrated with a neighborhood festival attended by the city's mayor, Jaume Collboni, and the councilor for the Sant Andreu district, Marta Villanueva.
