Vaikaradhoo (Dhivehi: ވައިކަރަދޫ) is one of the inhabited islands of Haa Dhaalu Atoll administrative division of the Maldives.

The ruins of a hawaitta (archeological mounds) known locally as the Jaadi Valhulithan stand on the western periphery of the island.

The apparent remains of a mosque created by early inhabitants of Vaikaradhoo are found on the nearby uninhabited island of Vaikaramuraidhoo.

Vaikaradhoo was one of the islands severely damaged by the great cyclone of 1821 that hit the northern atolls of the Maldives.

In 2011, the local council election was won by candidates of the ruling Maldivian Democratic Party, including Abdullah Nishan, Ahmed Waheed (President), Abdullah Shareef (Vice President), Ali Amir and Adam Shahid.

After World War II, the island became notable for a high literacy rate and awareness of general knowledge.

In 1984, with the help of Japanese grants to Maldives, five schools were built with administrative offices and lodging.

The island specialized in producing a few varieties of short-term crops, including watermelon, scotch bonnet pepper, green chili, papaya, taro, and pumpkin.

From the beginning of the 19th century, they were the largest producer of finger millets in the country, which helped them to stave off starvation during World War II.

Finger millet (Binbi) and screwpine (Kashi-keyo) fruits were largely traded between Raa atoll people in exchange of goods or money.
