Princess Jeongsin (1366 — 1421) was a Goryeo Royal Princess as the second daughter of King Gongyang and Royal Consort Sun.

Biography
On 17 April 1390, she was honoured as Princess Jeongsin along with her sisters, then married with Woo Seong-beom  whom later honoured as Prince Danyang. However, in July 1392, after Yi Seong-Gye's ascension to the throne and made the new dynasty, Woo was sentenced to death and was beheaded along with Gang Hoe-gye, her younger brother-in-law.

Woo Seong-beom came from the Danyang Woo clan who was the eldest son of Woo Hong-su  and the grandson of Woo Hyeon-bo. With Woo, she had one issue, a daughter. While the Princess's father-in-law tried to conspired, it was failed and died after being executed by Taejo's royal troops in 23 August.
