Murong Jun (319–360), courtesy name Xuanying, formally Emperor Jingzhao of (Former) Yan, is an emperor of the Chinese state Former Yan.

He is the state's second ruler, but after first using the Jin Dynasty (265-420)-created title of Prince of Yan, is the first to use the imperial title, as during his reign the state expands from possessing merely modern Liaoning and parts of Hebei to nearly all of the territory north of the Yellow River and some substantial holdings south of the Yellow River.
