The Our Ukraine–People's Self-Defense Bloc (Блок Наша Україна–Народна Самооборона, Blok Nasha Ukrayina-Narodna Samooborona, OU-PSD) is an electoral alliance active in Ukraine, associated with President Viktor Yushchenko. Since 2005, the bloc has been dominated by a core consisting of the People's Union "Our Ukraine" party and five smaller partner parties.
The Our Ukraine Bloc is most closely associated with the Orange Revolution and continues to use orange as its political colour. In July 2007, the old Our Ukraine bloc had been reorganized into the Our Ukraine–People's Self-Defense Bloc for the 2007 parliamentary election in September 2007. The member parties had planned to merge into a single party in December 2007 but on November 16, 2007 People’s Self-Defense decided to end its participation in the process of forming a united party since then that process is unclear. The alliance currently holds 72 out of 450 parliamentary seats.

Our Ukraine-People's Self Defence bloc received 14.16% of the vote, 236964 less votes in 2007 than the Our Ukraine bloc received in 2006, representing an overall swing of 0.20%.
On October 15, 2007, despite the Party of Regions gaining the most seats of all participating political parties, Our Ukraine–People's Self-Defense Bloc and the Yulia Tymoshenko Bloc agreed to form a majority coalition in the new parliament of the 6th convocation. On November 29, a coalition was signed between the Yulia Tymoshenko Bloc and Our Ukraine–People's Self-Defense Bloc (representing 45% of the national vote). On 18 December 2007 Yulia Tymoshenko, with a margin of two votes, was elected Prime Minister.
