Leiocephalus greenwayi, commonly known as the East Plana curlytail and the Plana Cay curlytail lizard, is a species of lizard in the family of curly-tailed lizards (Leiocephalidae).

The specific name, greenwayi, is in honor of American ornithologist James Cowan Greenway.

[3] L. greenwayi is endemic to the Bahama Islands and has an extremely restricted range as it is only found on the Eastern island of the Plana Cays.

[2] The preferred natural habitat of L. greenwayi is shrubland.

[4] This species of curly-tailed lizard, L. greenwayi, is not listed by the IUCN or CITES as needing any special conservation, however, research is needed to determine its vulnerability due to its restricted range.
