Inthawichayanon (Thai: อินทวิชยานนท์, RTGS: Inthawichayanon, Indavijayānanda, Thai pronunciation: [in.tʰa.wí.tɕʰa.jaː.non]; Northern Thai: , c. 1817 – 23 November 1897) was the 7th Ruler of Chiang Mai and Ruler of Lanna from 1870 until his death in 1897. His daughter, Princess Dara Rasmi of Chiang Mai became King Rama V's Princess Consort. During his reign the ties of the previously independent tributary state with the central government in Bangkok were intensified, culminating in the creation of the Monthon Phayap in 1892, by which Lanna was formally annexed.
