Sima Liang (司馬亮) (died 291), courtesy name Ziyi (子翼), formally Prince Wencheng of Ru'nan (汝南文成王), was briefly a regent during the reign of Emperor Hui during Jin Dynasty (265-420). He was the first of the eight princes commonly associated with the War of the Eight Princes.

Sima Liang was the fourth son of Sima Yi, by his concubine, Lady Fu. During Cao Wei regencies of his older brothers Sima Shi and Sima Zhao, he served as a mid-level official. After his nephew Sima Yan took the throne as Emperor Wu of Jin, ending Cao Wei and starting Jin, Sima Liang was created the Prince of Fufeng and put in charge of the military commands of Qin (秦州, modern eastern Gansu) and Yong (雍州, modern central and northern Shaanxi) provinces. In 270, after his subordinate, the general Liu Qi (劉旂) was defeated by the Xianbei rebel Tufa Shujineng, Sima Liang tried to have Liu's life spared by claiming fault; Liu's life was spared, but Sima Liang lost his post as a result.

Despite this, Sima Liang was well respected among the Jin imperial clan for his virtues, including his filial devotion to Princess Dowager Fu. Because of this, Emperor Wu put him in charge of monitoring the imperial princes' behavior, to correct and rebuke them when necessary.

In 277, Emperor Wu moved Sima Liang's principality to Ru'nan and put him in charge of the military commands of Yu Province (豫州, modern eastern Henan). However, soon he recalled Sima Liang back to the capital to serve as a high-level advisor.

As Emperor Wu grew ill in 289, he considered whom to make regent. He considered both Empress Yang Zhi's father Yang Jun and Sima Liang. As a result, Yang Jun became fearful of Sima Liang and had him posted to the key city of Xuchang. Several other imperial princes were also posted to other key cities in the empire. By 290, Emperor Wu resolved to let Yang and Sima Liang both be regents, but after he wrote his will, the will was seized by Yang Jun, who instead had another will promulgated in which Yang alone was named regent. Emperor Wu died soon thereafter and was succeeded by Emperor Hui. By this point, Sima Liang had not yet gone to Xuchang, but was fearful of Yang Jun, and so did not dare to attend Emperor Wu's wake. Yang was still suspicious that Sima Liang might have a coup in mind, and so prepared for his troops to attack Sima Liang. (Indeed, the justice minister He Xu (何勗) suggested to Sima Liang that he overthrow Yang, but Sima Liang refused.) In order to avoid a military confrontation with Yang, Sima Liang immediately left for Xuchang.
