Liu Yan (died 234), courtesy name Weishuo, was a long serving official in the state of Shu Han during the Three Kingdoms of China having served under the much travelled warlord Liu Bei during the late Eastern Han dynasty. Handsome and well spoken, he achieved high rank and favour but there were questions about his abilities, with his rank more honorary then powerful in practise, and he had a drinking problem. Nearly sacked after a fall out with Wei Yan, accusations about his wife and the Emperor saw him executed in disgrace.
