Deep Rooted Tree (Korean: 뿌리 깊은 나무; RR: Ppuri Gipeun Namu) is a 2011 South Korean television series starring Han Suk-kyu, Jang Hyuk and Shin Se-kyung. Based on the novel of the same name by Lee Jung-myung, it aired on SBS from 5 October to 22 December 2011 on Wednesdays and Thursdays at 21:55 for 24 episodes.

Taking its name from the poem Yongbieocheonga that says that trees with deep roots do not sway, the series tells the story of a royal guard (played by Jang Hyuk) investigating a case involving the serial murders of Jiphyeonjeon scholars in Gyeongbok Palace while King Sejong (played by Han Suk-kyu, in his TV comeback after 16 years of solely film work) comes to create the Korean alphabet.
