Ukrainian Democratic Alliance for Reform

A political party in Ukraine headed by retired Ukrainian professional heavyweight boxer Vitali Klitschko. The party has been an observer, and later an associate member of the European People's Party (EPP) since 2013.

The party's original name was Political Party "European Capital", founded in March 2005 by businessman Lev Partshaladze. On 24 April 2010, it was renamed Ukrainian Democratic Alliance for Reform and elected boxer Vitali Klitschko as its leader, following its participation in the Vitali Klitschko Bloc, during the 2008 Kyiv local election.

The party won 40 seats in the 2012 Ukrainian parliamentary election.

In the 2014 parliamentary election, 30% of the Petro Poroshenko Bloc election list was filled by members of UDAR (as non-partisan) and UDAR leader Klitschko topped that list. The Petro Poroshenko Bloc won the election with 132 seats. UDAR officially merged into the Petro Poroshenko Bloc on 28 August 2015.

In May 2019 Klitschko announced that UDAR would take part independently in the 2019 Ukrainian parliamentary election. In this election UDAR did compete as an independent party again, but only in 15 single-mandate constituencies and it failed to win any seats.

In the 2020 Kyiv local election UDAR won 30 of the 120 seats of the Kyiv City Council. In the same election Klitschko was reelected as Mayor of Kyiv with 50.52% of the votes.
