This is a Marquesan style tiki mug in orangish "coral" glaze. There are also versions in sage stain with green wash, in orange with black wash, or in blue with black wash.

From the Tiki Farm website:

"Now available in a Coral glaze, our popular Marqool is a straight-up Marquesan-inspired Tiki mug. There is not much of a deviation here from what you would have expected 21-years ago from Tiki Farm in that regard. Marqool was created by our friend and longtime Tiki Farm contributing artist/designer – Tank Standing Buffalo.
