Line D of the Buenos Aires Underground runs from Catedral to Congreso de Tucumán. The D Line opened on 3 June 1937 and has been expanded to the north several times. The line is currently 11 km long and has 16 stations, while running approximately parallel to the city's coastline.

Line D was the second line to be built by the Hispanic-Argentine Company for Public Works and Finances (CHADOPyF), following the construction of Line C in 1934. Construction began in 1935 and the first part of the line was inaugurated in 1937 and ran 1.7 km from Catedral (still the current terminus) to Tribunales. Three years later, the section which brought the line to Plaza Italia in Palermo was completed, bringing the length of the line to 6.5 km.

The line was not properly extended until 1993 when it was extended to Ministro Caranza, a station named after the Radical politician. Further extensions occurred in the 1990s, beginning in 1997 with the aperture of Olleros and José Hernández, then Juramento in 1999, and finally Congreso de Tucumán in 2000, where it currently terminates.

Over the decades it has been discussed numerous times whether to extend the line out to the limits of the city proper. The last of these proposals came forward in 2002 which would have seen an additional two stations added to the line. However, this was later abandoned since the line was already at full capacity after the opening of Congreso de Tucumán station. In June 2015 the Metrobus Cabildo line opened, connecting Line D from its terminus at Congreso de Tucumán to Vicente López district in Greater Buenos Aires, some kilometres away from the city limits, essentially making the extension of Line D redundant. Line D is the only line in the network which will not be extended as part of the most recent expansion plan.
