Zhuge Dan was from Yangdu County (), Langya Commandery (), which is in present-day Yinan County, Shandong. He was a descendant of Zhuge Feng () and a cousin of Zhuge Jin and Zhuge Liang. He started his career as a Gentleman of Writing (). There was once when he and Du Ji, a Supervisor (), test-rode a boat in the river. The boat capsized after being hit by a wave and both men were thrown overboard. When the "huben" guards came to save him, Zhuge Dan told them to save Du Ji first. He lost consciousness later, drifted to the shore, and eventually recovered.
