Setting for many Gauguin works (6)
I believe the answer is:
tahiti
(Other definitions for tahiti that I've seen before include "Pacific island associated with Gauguin" , "South Pacific island where both Robert Louis Stevenson and Paul Gauguin spent time" , "part of Polynesia" , "Romantic Polynesian island, capital Papeete" , "An isle in the South Seas" .)
