The 2017–2018 Russian protests were a long series of countrywide street protest actions and demonstrations in the Russian Federation, which were primarily concerned with suppressing corruption in the Russian government (from 26 March 2017 through spring 2018) and abandoning the planned retirement age hike (from 14 June 2018 through the end of 2018).

The anti-corruption protests began in March 2017 but were joined by and overlapped the 2018 Russian pension protests. The anti-corruption protests were primarily led by Alexey Navalny, who was joined by well-known participants such as the Libertarian Party, Open Russia, and Artpodgotovka. They occurred as a result of the Russian financial crisis (2014–2016) aftermath, although they had their root in the corruption at the different levels up to the highest echelons of the Russian power.

The protests and demonstrations against corruption in the Russian government began in March 2017 after the release of the investigative film He Is Not Dimon to You by Navalny's Anti-Corruption Foundation, at a point when the country was already tense. Discontentment was triggered by the alleged corrupt activity of Prime Minister Dmitry Medvedev as presented in the film, the inadequately planned demolition of apartments in Moscow and the protracted strikes of truck drivers related to the Platon toll system, which had been ongoing since 2015.

National protests against alleged corruption in Russia took place simultaneously in more than 100 cities across the country on 26 March 2017. They were caused by the dismissive response from the Russian authorities to the published investigative film He Is Not Dimon to You, which had garnered more than 23 million views on YouTube. By Sunday evening, riot police in body armor and helmets had detained more than 1000 demonstrators in central Moscow, as the crowd, numbering in the tens of thousands, cheered, whistled and chanted "Shame!", "Medvedev, resign!", and "Putin is a thief!" The Levada Centre survey showed that 38% of surveyed Russians supported the protests and that 67% held Putin "entirely" or "to a large extent" responsible for high-level corruption.A new wave of mass protests occurred on 12 June 2017. After the arrest of Navalny on 29 September, hours before a planned rally in Nizhny Novgorod, a new wave of protests was announced for 7 October, the birthday of Putin. Protests and uprisings continued in 2018, with the tendency to radicalization, and a record number of protesters was detained on 5 May, two days before Putin's inauguration. Mass rallies were held in more than 60 cities all over Russia.
