The pardoned political prisoners consist of seven women and 23 men, according to the presidential office in Minsk.
"Most of them are parents of minors and small children," the office states in a statement where the pardon is called a "gesture of humanity".
According to human rights organizations, nearly 1,400 Belarusians are still imprisoned for protesting against Lukashenko's authoritarian regime, which after the controversial presidential election in 2020 brutally suppressed all forms of criticism against the government.
Last week, the leader of the exiled opposition, Svetlana Tikhanovskaya, considered by many to be the true winner of the 2020 election, warned that protest leader Maria Kolesnikova is being subjected to a "slow murder" in the prison where she is being held.
In August, 30 people who were convicted of participating in Belarus' regime-critical protests were also released.
