Our Ukraine–People's Self-Defense Bloc

The Our Ukraine–People's Self-Defense Bloc (Ukrainian: Блок Наша Україна–Народна Самооборона, Russian: Блок Наша Украина – Народная Самооборона, Blok Nasha Ukraina – Narodnaya Samooborona, NUNS; until 2007 named Our Ukraine Bloc) was an electoral alliance active in Ukraine from 2001 until 2012, associated with former President Viktor Yushchenko. Since 2005, the bloc had been dominated by a core consisting of the People's Union "Our Ukraine" party and five smaller partner parties. On 17 November 2011, the Ukrainian Parliament approved an election law that banned the participation of blocs of political parties in parliamentary elections. Since then several members of the Bloc have since merged with other parties.

The Our Ukraine Bloc was most closely associated with the Orange Revolution and continued to use orange as its political colour even after the Orange Revolution had ended. In July 2007, the old Our Ukraine bloc was reorganized into the Our Ukraine–People's Self-Defense Bloc for the 2007 parliamentary election in September 2007.
