About 300 people gathered to watch the statue be lifted from its plinth in a park and placed on a flat-bed truck at a ceremony, the BBC reported.
Mayor Bat-Uul Erdene gave a 10-minute speech at the ceremony, during which he denounced Lenin and his fellow communists as "murderers."
Bat-Uul said the statue would be auctioned off with a starting price of about $280.
