Second place went Grace Bay,Providenciales,in the Turks and Caicos,while Australia's own Whitehaven Beach in Queensland came third.
"Rabbit Beach's is clearly a big hit with travellers and it's easy to see why with its stunning turquoise water and white sand,"said TripAdvisor spokeswoman Emma Shaw,adding that the award would be a boost for Sicily's tourism.
Beaches in Brazil,Spain,Puerto Rico,Bermuda and Aruba also featured in the top 10,praised for their white sands and swaying palm trees.
Whitehaven Beach is on Whitsunday Island,the largest island in the Whitsundays. The pristine silica sand of the beach stretches over seven kilometres along the island,and the beach has previous been named among the world's and Australia's best.
There was one big surprise in the TripAdvisor list:coming 10th was Rhossili Bay in Swansea,Wales,which beat beaches in Hawaii,the Caribbean and more exotic locations to make the top 10 list.
