"Statutes of the two beautiful muses of the great revolutionary and founder of the Soviet state should be erected in St. Petersburg, on Lenin Square," the Communists of Petersburg and the Leningrad Region said in a statement.
The group, notorious for its bizarre initiatives, said a statue of Lenin's wife Nadezhda Krupskaya should be placed to the right of his statue, and one of his mistress, Inessa Armand, should go on his left.
"The women who won the heart of Vladimir Lenin knew the art of love, were good cooks, maintained cleanliness, and were companionable and house-proud," the statement said, adding that Lenin could have fallen in love only with an "outstanding woman."
The group said it was announcing the fundraising campaign to mark International Women's Day, celebrated in Russia and several other countries on March 8.
The communist group, which is a separate to the national Communist Party, earlier made headlines in Russia by criticizing soccer star Andrei Arshavin for "displaying for sale his body for many months in front of covetous Western clubs."
It also accused the latest Bond girl, Ukrainian Olga Kurylenko, of a "moral and intellectual betrayal" in starring in a movie about the "enemy of the Soviet people."
None of their initiatives have yet been successful.
