Ilya Valeryevich Yashin (Russian: Илья́ Вале́рьевич Я́шин; born 29 June 1983) is a Russian opposition politician who led the People's Freedom Party (PARNAS) from 2012 to 2016, and then its Moscow branch. He was also head of the Moscow municipal district of Krasnoselsky and former chairman of the Council of Deputies of the Krasnoselsky district from 2017 to 2021.^[1]

Yashin co-founded the civic youth movement Oborona in 2005 and later the political movement Solidarnost in 2008, of which he is still one of the leaders. He was an active participant in the Dissenters' March and the 2011–2013 Russian protests. In 2012, he was elected to the Russian Opposition Coordination Council. Amidst an increase in government crackdowns on the opposition following the 2022 Russian invasion of Ukraine, some considered Yashin to have had the largest platform of any opposition politician that had not either left the country, been imprisoned, or been killed.^[2][3][4][5] In June 2022, he was arrested, and later accused under the new war censorship laws of disseminating fake news about the Armed Forces. In December 2022, he was sentenced to 8+1⁄2 years in prison.^[6]
