Havana's land (4)
I believe the answer is:
cuba
'havana's land' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cuba that I've seen before include "Largest Caribbean island" , "Guantanamo Bay location" , "Large Caribbean island" , "Country famous for its cigars" , "Its capital is Havana" .)
