Opposition Bloc, formerly called Opposition Bloc — Party for Peace and Development until June 2019, was a Ukrainian political party that was founded in 2019. On 8 June 2022, the party was banned in court. The party officially ceased to exist on 25 July, due to not appealing the ban.

Presidential elections were held in Ukraine on 31 March 2019. As none of the 39 candidates on the ballot received an absolute majority of the initial vote, a runoff was held on 21 April between the top two vote-getters, Volodymyr Zelenskyy, a television personality, and the incumbent president, Petro Poroshenko. According to the Central Election Commission (CEC), Zelenskyy won the second round with 75% of the vote. The elections were recognized as free and fair.
