Ales Viktaravich Bialiatski (Belarusian: Алесь Віктаравіч Бяляцкі, romanized: Alieś Viktaravič Bialiacki; born 25 September 1962) is a Belarusian pro-democracy activist and prisoner of conscience known for his work with the Viasna Human Rights Centre. An activist for Belarusian independence and democracy since the early 1980s, Bialiatski is a founding member of Viasna and the Belarusian Popular Front, serving as leader of the latter from 1996 to 1999. He is also a member of the Coordination Council of the Belarusian opposition. He has been called “a pillar of the human rights movement in Eastern Europe” by The New York Times, and recognized as a prominent pro-democracy activist in Belarus.

Bialiatski’s defence of human rights in Belarus has brought him numerous international accolades. In 2020, he won the Right Livelihood Award, widely known as the “Alternative Nobel Prize”. In 2022, Bialiatski was awarded the 2022 Nobel Peace Prize, along with the organizations Memorial and Centre for Civil Liberties.

Bialiatski has been imprisoned twice; firstly from 2011 to 2014, and currently since 2021, on both occasions on charges of tax evasion. Bialiatski, as well as other human rights activists, have called the charges politically motivated.

On 3 March 2023, Bialiatski was sentenced in Minsk to ten years in prison for “cash smuggling” as well as “financing actions and groups that grossly violated public order.” Human rights activists view the charges as fabricated in order to silence Bialiatski and his movement after he was awarded the Nobel Peace Prize.
