Sinwol-dong (Korean: 신월동) is a dong (neighbourhood) of Yangcheon District, Seoul, South Korea.

[1][2] During the Gabo reform during the 31st year of reign of King Gojong, the administrative district was reorganized from Yangcheon-hyeon (縣) to Gun (郡), and when Sinwol was incorporated into Gimpo-gun in 1914, the administrative district changed to Sindang-ri, Yangdong-myeon, Gimpo-gun.

The name Sindang-ri derives from the name of the village of "Sinwol and Danggok."

"Shindae" means Newly founded village.

[3] The words "Sinwol" and "Gateri" derive from the shape of the region, and are said to be the same shape as the half-moon on the east side of Jeungsan (currently Sinwol 3-dong area).
