Pyone Cho (Burmese: ပြုံးချို); born Htay Win Aung; born 2 April 1966), whose name means "sweet smile" in Burmese, is an activist and former political prisoner, who served as a Member of Parliament (MP) in the House of Representatives for Dawbon Township in Yangon, from 2015 to 2021.

He is an internationally recognized human rights activist, as well as a former student organizer and leader of the 8888 Uprising in Myanmar.

Because political prisoners were denied the right to read and write (they were not allowed to have pens or pencils in their possession), the military government added another seven years to his sentence in 1996.

[2][11] Pyone Cho's younger brother, Thet Win Aung, was also an internationally recognized human rights figure.

Thet Win Aung died in Mandalay Prison at the age of thirty-five, after being imprisoned and tortured for engaging in peaceful acts of protest.
