Zhèng Jízhī 鄭輯之 (fl. Liu Song dynasty, 5th century CE) was a geographic writer and official, author of a Yǒngjiā jùn jì 永嘉郡記 (KR2k0193), a record of Yongjia Commandery (modern Wenzhou, Zhejiang). He served in some capacity in Yongjia. His work has sometimes been misattributed to Xiè Língyùn 謝靈運 (385–433 CE), who also wrote about the Yongjia region, but modern scholarship distinguishes the two. No further biographical details are attested.
