Waiting for a trolleybus, Leninskiy Prospekt, Moscow

Leninsky Avenue (Russian: Ле́нинский проспе́кт) is a major avenue in Moscow, Russia, that runs in the south-western direction between Kaluzhskaya Square in the central part of the city through Gagarin Square to the Moscow Ring Road.

The location of the current avenue has been a road since before the 18th century. Only the area between Kaluzhskaya Square and Kaluzhskaya Zastava Square (currently Gagarin Square) was then included into Moscow, and the name of this stretch was Bolshaya Kaluzhskaya Street. Construction was active in that area between the 18th century and the 1940s.

It is the second widest street in Moscow after Leningradsky Avenue. Its width varies between 108 and 120 metres.
