Jayang-dong (Korean: 자양동) is a dong (neighborhood) of Gwangjin District, Seoul, South Korea.

[1][2] During the Joseon period, the name of Jangyang-dong was "Jamajang" (雌馬場), which translates to "female horse field."

In the early days of the Joseon Dynasty, there was a legend that if one were to raise a thousand horses, a mythical creature called Yongma (龍馬), a dragon-horse, would be born.

Jangyang-dong, being an area where fertile sediments flowed through the Han River and accumulated, had vast natural fields, making it advantageous for grazing horses.

As a result, a significant number of female horses were raised in this area.
