Quarto Oggiaro is a district ("quartiere") of Milan, Italy, part of the Zone 8 administrative division, north-west of the city centre. It is adjacent to the comunes of Novate Milanese and Baranzate, and to districts Vialba, Villapizzone, Bovisasca, and Comasina.
The name "Quarto Oggiaro" comes from an older toponymy "Quarto Uglerio". "Quarto", meaning "fourth", is a reference to the fact that the ancient settlement was four roman miles from the centre of Milan. The meaning of "Uglerio" is unknown, but it is supposed to be the name of some influent inhabitant of the area in ancient times.
Quarto Oggiaro was a fraction of Musocco when this became part of Milan, in 1923. The district developed in the 1950s, to provide low-income housing for the large number of immigrants that were relocating to Milan from Southern Italy. Construction of apartment blocks continued in the 1960s. In those early decades, Quarto Oggiaro had virtually no public services, so that it was essentially a "dormitory" district. This gradually changed in the last decades of the 20th century.
The prominent building in Quarto Oggiaro is arguably Villa Scheibler, dating back to the 15th century, originally a hunting villa of Ludovico Sforza.
Quarto Oggiaro is richly connected to the city by railway, tramway, and bus lines.
