Terakado Seiken (寺門静軒) (1796 – April 16, 1868) was a Confucian scholar who lived in Japan during the Edo period.

After his father's death he lived a delinquent lifestyle before turning to Confucianism and eventually opening a school.

The essays were banned by Edo officials in 1835, and after publication the woodblocks the book was printed with were confiscated in 1842.

After losing his position as a samurai Terakado wandered Japan and worked as a schoolteacher and writer.

[1] He also frequently juxtaposed the upper and lower classes to shed more light on the economic inequalities within the Tokugawa government's system.
