Yi Ryang (; 17 November 1519 - 8 March 1583), also spelle Lee Lyang, was a powerful politician during the Joseon period. His courtesy name was Gonggeo .
Yi Ryang was a member of the ruling Jeonju Yi clan and was a great-great-great-grandson of Grand Prince Hyoryeong through his son Yi Gab, Prince Boseong.
His older sister, Lady Yi, was the wife of Sim Kang. Their daughter, Lady Sim, married Grand Prince Gyungwon, a son of King Jungjong, who later became Myeongjong of Joseon.
In his early years, Yi Ryang studied at Chung Sa-ryong's private academies.
In 1546, he passed to Saengwon and Chinsa exams and in 1552, he passed the Imperial examination. Yi Ryang worked in the Inspection Department.
In 1550, there was tension with Yun Won-hyeong's group of supporters, who were trying to take more government power at the time, and Yi Ryang was promoted rapidly under the auspices of King Myeongjong. He was promoted to second level bureaucrat after only two years.
In 1563, it was discovered that Yi Ryang had illegally accumulated wealth. As a result, he was ousted from the government, but his punishment was lessened due to Yun Won-hyeong's intervention.
Yi Ryang died in exile on March 8, 1583.
