Jatupat Boonpattararaksa (Thai: จตุภัทร์ บุญภัทรรักษา), commonly known as Pai Dao Din (ไผ่ ดาวดิน; a combination of his nickname Pai and the student activist group Dao Din) is a human rights defender and activist from Thailand, who was arrested on 3 December 2016 on charges of Lèse-majesté in Thailand, the first such case under King Vajiralongkorn,[1] following which he faced a secret trial and was then imprisoned.

His father, Viboon Boonpattararaksa, is a community lawyer who has sought to represent villagers assassinated on social justice cases, such as protecting the environment.

[5] Following the 2014 coup, while the military junta (the National Council for Peace and Order; NCPO) was successfully repressing pro-democracy activists with diktats restricting freedom of expression, Pai and other Dao Din members peacefully protested Prime Minister General Prayut Chan-o-cha at a function in Khon Kaen by flashing the three-finger Hunger Games salute in front of him.

3/2015 for participating in a gathering of over five people on 22 May 2015 to commemorate the May 2014 coup d’état, Jatupat was taken to the Military Court of Khon Kaen Province for trial together with seven other democracy activists.

[12] Jatupat was accused of lèse majesté and was arrested on 3 December 2016 for "sharing" on his Facebook page a BBC Thai biography of King Vajiralongkorn as well as distributing material against Thailand's draft constitution.

[20] On 21 December 2017, while facing another charge related to holding an activity “Speaking for Freedom”, he testified at the military court at the Sripatcharin Camp of 23rd Royal Army Base while wearing his university graduation gown over his prison uniform.

[2] On 7 January 2018, local villagers in Wang Saphung District, Loei Province, while issuing a statement regarding their struggle to protect the community and environment from gold mining, wore Jatupat masks in a show of solidarity.

[21] After being released from prison, Jatupat became an official aide to MP Rangsiman Rome and had a role in Thailand's Parliament as Secretary of the Parliamentary Commission on Law, Justice, and Human Rights, and member of the Select Committee to Study and Solve the Problem of Infringement of Human Rights and Covert Harms to Citizens in affiliation with the Future Forward group.

[11] Jatupat sings and performs in the song and YouTube music video "คนที่คุณก็รู้ว่าใคร" ("You Know Who") with the band สามัญชน Commoner, released 3 February 2021, which draws attention to 9 assassinated Thai political dissidents.
