Michu was the thirteenth ruler of the Korean state of Silla (r. 262–284). He was the first king of the Kim clan to sit on the Silla throne; this clan would hold the throne for most of Silla's later history. He was the son of Gudo, a leading Silla general, and the sixth-generation descendant of the clan founder Kim Alji.
During Michu's reign, the Samguk sagi reports numerous attacks from Baekje, and does not mention any contact with the other neighboring states.
