Korso is a district and major region in Helsinki metropolitan area, in northeastern Vantaa, Finland.
According to the Vantaa neighbourhood division, Korso is bordered by the railway tracks to the east, by Vallinoja to the north and by Vierumäki to the northwest.
At the end of the 19th century, an overtake point was needed on the main railway track line halfway between Tikkurila and Kerava.
It also included the Korso railway station, whose neighbourhood formed a clearly separate residential point from the centre of the market town.
This caused administrative problems, and because of them Korso was wholly incorporated in Helsingin maalaiskunta in the beginning of the year 1954.
The building of the Maarukanmetsä residential area started in the early 2000s in the southeastern part of Mikkola and continues to be built to this day.
Also to the east of the railway tracks are a child care station and the Korso-Rekola psychiatric policlinic and a Christian parish of Korso.
Korso's dental care station and the Korson koulu school are also located to the west of the railway tracks.
It also has bus connections via the Peijas hospital to Mellunmäki, Tikkurila, Kerava, southern Päiväkumpu, Hyrylä, Myyrmäki and the Helsinki Airport.
