Guo Youzhi ( third century), courtesy name Yanchang, was an official of the state of Shu Han in the Three Kingdoms period (220–280) of China. Zhuge Liang, the Imperial Chancellor of Shu, described Guo Youzhi in the Chu Shi Biao as exceedingly loyal and faithful, and named him along with Dong Yun and Fei Yi as the more competent officials in Shu while advising the Shu emperor Liu Shan to make good use of their talents.

郭攸之？ - ？，字演长，南阳人，为人和顺，以器识才学知名于时。先前一同费禕和董允为刘备提拔。建兴元年（223年），当时担任中郎的郭攸之被廖立评价，说自身只有顺从他人，不足担任大事，只能担任侍中而已。二年（224年）任蜀汉黄门侍郎，后迁主簿。诸葛亮在出师表中曾经推荐给刘禅的贤能之一，然而在诸葛亮北伐的时候，攸之和顺的性格只能被担任为后备人员。
