Ono no Takamura (小野 篁?) also known as Sangi no Takamura (参議篁?, 802 – February 3, 853) was an early Heian period scholar and poet.
Takamura was a descendant of Ono no Imoko who served as Kenzuishi, and his father was Ono no Minemori. He was the grandfather of Ono no Michikaze, one of the three famous calligraphers (三筆 sanpitsu?). In 834 he was appointed to Kintōshi, but in 838 after a quarrel with the envoy, Fujiwara no Tsunetsugu, he gave up his professional duties pretending to be ill, and attracted the ire of retired Emperor Saga, who sent him to Oki Province. Within two years he regained the graces of the court and returned to the capital where he was promoted to Sangi.
Takamura is the subject of a number of odd stories and legends. One of the most singular of these legends is the claim that every night he would climb down a well to hell and help Yama (閻魔大王 enma daiō?) in his judgements (裁判 saiban?). In Sataku, Kyoto, there is a grave said to belong to Takamura. Near that grave is a grave marked Murasaki Shikibu, with a legend that it was placed there by the devil himself as punishment for lust (愛欲 aiyoku?) for which Murasaki Shikibu descended to hell.
