Royal Consort Sug-ui of the Geochang Shin clan (Korean: 숙의 신씨; Hanja: 淑儀 愼氏; 1436–1476) was a concubine of Crown Prince Yi Jang, the eldest son of King Sejo of Joseon.^[1]

The future Royal Consort Sug-ui was born in 1436 as the eldest daughter and child of Shin Seon-gyeong and Lady Han of the Cheongju Han clan. She had five younger siblings; three sisters and two brothers.

Through her maternal grandfather, she was a second cousin to Han Myeong-hoe, and second cousins once removed to Queen Jangsun and Queen Gonghye as they shared Han Su (한수; 韓脩; 1333–1384) as their great-great-grandfather.

On August 23, 1456 (lunar calendar), she was selected to become the concubine of Crown Prince Uigyeong and was granted the title Consort So-hun (junior 5th rank concubine of the Crown Prince; 소훈, 昭訓).^[2] She entered the palace on that same year.^[3]

In 1457, the Crown Prince passed away and left no issue with the consort.

When her husband was honored as King, Lady Shin was promoted to the 2nd junior rank concubine of the King (숙의; 淑儀) as Royal Consort Sug-ui.

She died on May 16, 1476 (lunar calendar), during the 7th year of King Seongjong's reign.
