The Union Solidarity and Development Party (USDP; Burmese: ပြည်ထောင်စုကြံ့ခိုင်ရေးနှင့် ဖွံ့ဖြိုးရေးပါတီ, romanizedpyihtaunghcukyaanhkinerayynhang hpwanhpyaoerayyparte) is an ultranationalist, pro-military political party in Myanmar. Alongside the National League for Democracy, it is one of Myanmar's two principal national parties.

USDP is the successor to the former ruling military junta's mass organisation, the Union Solidarity and Development Association (USDA), and serves as the electoral proxy of the Tatmadaw (military), which operates as a state within a state. Many of its political candidates and leadership are retired generals. It supports authoritarian military leadership. USDP was founded by Prime Minister Thein Sein to contest the 2010 Myanmar general election; the party was headed by Sein until 2013. Since 2022, it has been led by Khin Yi, who was installed as a loyalist of military leader Min Aung Hlaing.
