Samyang-dong () is a dong (neighbourhood) of Gangbuk District, Seoul, South Korea. On June 30, 2008, former Mia-1 and 2 dongs are combined for this dong.
In 1949, when Miari was incorporated into the Seoul Metropolitan Government, district mayors gathered together and established an administrative neighborhood name with the meaning of "Neighborhood in the sunny south of Samgaksan Mountain."
