Paska is a Ukrainian Easter bread. It is particularly spread in Central and Eastern Europe, and countries with cultural connections to the ancient Byzantine Empire, Eastern Orthodoxy or Eastern Catholicism. Easter breads are a traditional element in the Easter holidays of Armenia, Belarus, Bulgaria, Croatia, Georgia, Moldova, Romania, Russia, Poland, Slovakia and Ukraine. It is also a common tradition amongst the Assyrian-Chaldean-Syriac diaspora. It is also eaten in countries with large immigrant populations from Central and Eastern Europe such as the United States, Canada and the United Kingdom.

In many European countries, particularly in Central and Eastern Europe, there are various traditions surrounding the use of bread during the Easter holidays. Traditionally the practice of eating Easter bread or sweetened "communion" bread traces its origin back to Byzantium, Eastern Catholicism and the Orthodox Christian church. The recipe for sweetened or "honey-leavened" bread may date back as far as the Homeric Greek period based on anecdotal evidence from classical texts.
