The Urucum worm lizard (Amphisbaena leeseri) is a species of worm lizard in the family Amphisbaenidae. The species is endemic to central South America.
The specific name, leeseri, is in honor of Leo Leeser (1871–1942), who died in the Theresienstadt concentration camp, but whose estate funded the Leo Leeser Center for Tropical Biology.
A. leeseri is found in southwestern Brazil (Mato Grosso do Sul state) and in adjacent northern Paraguay.
A. leeseri is oviparous.
