Pacific Ocean sounds right - consider all the islands along Alaska, Japan, Okinawa, Taiwan, the Philippines, Indonesia, Polynesia, Micronesia, Melanesia, and the west coast of South America, Central America and North America...

Yes, it's the Pacific. The Pacific Ocean contains an estimated 20,000 to 30,000 islands:

The list of islands in the other oceans are not even close.

Yes.

Considering it has countries like the Phillipines (this alone probably has more islands than the Atlantic Ocean) and Indonesia plus all the Oceania countries.... YES, the Pacific Ocean has the most islands.

Congratulation! u have get it right. Pacific Ocean has the most islands.

The Pacific Ocean contains an estimated 20,000 to 30,000 islands; the exact number has not been precisely determined. These islands are also sometimes collectively called Oceania (although Oceania usually also includes Australia and New Zealand), and are traditionally grouped into three: Melanesia, Micronesia, and Polynesia. Inhabitants are sometimes referred to as Pacific Islanders.

Melanesia means black islands. These include New Guinea (the largest Pacific island, which is divided into the nation of Papua New Guinea and the Indonesian provinces of Papua and West Irian Jaya), New Caledonia, Vanuatu, Fiji, and the Solomon Islands

Micronesia means small islands. These include the Marianas, Guam, Wake Island, Palau, the Marshall Islands, Kiribati, Nauru, and the Federated States of Micronesia.

Polynesia means many islands. These include New Zealand, the Hawaiian Islands, Rotuma, the Midway Islands, Samoa, American Samoa, Tonga, Tuvalu, the Cook Islands, French Polynesia, and Easter Island.

There are also many other islands located within the boundaries of the Pacific Ocean, but these are not considered part of Oceania. These islands include the Galápagos Islands of Ecuador; the Aleutian Islands in Alaska; the Russian islands of Sakhalin and Kuril Islands; Taiwan; the Philippines; the South China Sea Islands; most of the islands of Indonesia; and the island nation of Japan, which includes the Ryukyu Islands. However, it should be noted that the inhabitants of these islands are not considered to be Pacific Islanders and are usually identified with their nearest continent.
