Yonggang-dong (Korean: 용강동) is a dong (neighbourhood) of Mapo District, Seoul, South Korea.

[1][2] Yonggang-dong was named after Yonggang-myeon, Goyang-gun, and it was named according to the Fengshui Geography that Mapo River is like a dragon's head.

The name of Tojeong-dong is derived from the fact that Ji-ham Lee, famous for his secret of Tojeong, built a pavilion out of soil.

On October 1, 1946, it became Yonggang-dong, Mapo District.

On April 18, 1955, the name was changed to Gwanran-dong, and on May 18, 1970, it became Yonggang-dong again.
