Lenina Square, Federal cultural heritage square in Petrozavodsk, Russia

Lenina Square is a central public space in Petrozavodsk located at the intersection of Karla Marksa Avenue and Fridrikha Engelsa Street. The area features pedestrian pathways, seating benches, and multiple entry points for easy access throughout the day.

The square dates to the 1770s, when Anikita Yartsov planned the centre of Petrozavodsk and eight stone administrative buildings were raised in a circle to designs by Yelizvoy Nazarov. In 1788 Mikhail Kiselnikov and Fyodor Kramer rebuilt six of them into two semicircles for provincial offices. It was renamed Petrovskaya in 1873, became Ploshchad 25 Oktyabrya after 1917, and took the name Lenina in 1960.

The square's name changed with each era: Kruglaya (Round) from its circular layout, Petrovskaya after the 1873 Peter I monument, then Soviet names, Administrativnaya under Finnish occupation, and Lenina Square in 1960. The National Museum of Karelia holds a permanent interactive exhibition on this history.

The square lies at the crossing of Karla Marksa Avenue and Fridrikha Engelsa Street, with the granite Lenin monument at its centre. The National Museum of Karelia, housed in the southern building, holds a permanent interactive exhibition on the square's history. The Ministry of Culture of the Republic of Karelia occupies the northern building, whose porch is flanked by lions cast at the Aleksandrovsky Plant in 1858.

The granite for Lenin's statue came from 14 blocks quarried by Gulag prisoners on Goltsy Island in Lake Onega. The figure weighs over 140 tonnes and stands 6.5 metres tall, 11 with its pedestal, the largest monument in the Republic of Karelia. It was unveiled on 7 November 1933.
