The Communist Party of Ukraine (CPU or KPU) is a banned political party in Ukraine. It was founded in 1993 and claimed to be the successor to the Soviet-era Communist Party of Ukraine, which had been banned in 1991. In 2002 it held a "unification" congress when both "old and new" parties merged. The party is a member of the Moscow-based Union of Communist Parties, an umbrella organisation for all communist parties of the former Soviet Union. The party has been led by Petro Symonenko since it was founded.
Communist parties have a long history in Ukraine. With the fall of the Soviet Union, members of the Soviet-era Communist Party of Ukraine formed the Socialist Party of Ukraine. After being revived in 1993, the Communist Party was represented in the Ukrainian parliament from 1994 until the 2014 Ukrainian parliamentary election, which ended a period of parliamentary representation for communists stretching back to 1918. The Communist Party and its predecessor were the largest party in Ukrainian parliamentary elections for the first eight years of free and fair election, from 1990 until 1998.
