The Warao are an Indigenous Amerindian people inhabiting northeastern Venezuela, Trinidad and Tobago, Guyana, and Suriname. Alternate common spellings of Warao are Waroa, Guarauno, Guarao, and Warrau. The term Warao translates as "the boat people", after the Warao's lifelong and intimate connection to the water. Most Warao inhabit Venezuela's Orinoco Delta region, with smaller numbers in neighbouring Guyana, Trinidad and Tobago, and Suriname. With a population of 49,271 people in Venezuela during the 2011 census, they were the second largest Indigenous group after the Wayuu people. They speak an agglutinative language, Warao.

Warao use canoes as their main form of transportation. Other modes, such as walking, are hampered by the hundreds of streams, rivulets, marshes, and high waters by the Orinoco River. Warao babies, toddlers, and small children are famed for their ability to hold tight to their mothers' necks, as well as to paddle. They often learn to swim before they learn to walk.

The Warao use two types of canoes. Bongos, which carry up to 5 people, are built in an arduous process that starts with the search for large trees. When an old bongo is no longer usable, a consensus is reached by the leaders of each household on which tree is best. At the start of the dry season, they find the tree and kill it. At the end of the dry season, they return to cut it down. It is then hollowed out and flattened with fire and stone tools traded from the mountains (or local shell tools). Traditionally, the work of making the larger canoes by the young men is done with instructions from the elder female of the household, handed down by her daughters to their husbands.

The other type of canoe is small, seating only three people, and is used for daily travel to and from food sources.

The Warao diet is varied with an emphasis on the products of the delta, mostly fish. By 1500 they had acquired basic horticulture; many of their daily fruits and vegetables come from the domesticated and cultivated Palm orchards of the delta. In July and August, Warao feast on crabs when they come to the delta from the beach. Hunting is generally avoided due to cultural taboos. They occasionally also eat grubs found in the moriche palm tree. Pith of the palm was also eaten, but contemporary consumption is more likely to have it added as an additional ingredient for cassava bread.

The Warao are, according to their own reports, descended from an adventurous heavenly figure — the primordial hunter. This man originally dwelt in a sky world which had men, but was completely devoid of all animals except birds. Hunting these heavenly birds, the founding man used his bow and arrow to strike a bird in mid-air. The bird fell from the sky and eventually hit the heavenly floor. The birds burst through the floor and proceeded through the clouds and towards terrestrial land (Earth) below. The hunter went to the hole in the floor made by the bird and looked through. He saw lush and fertile land (Earth) and resolved to descend to it to partake of its pleasures: beauty, abundant game, fruit, et cetera. The hunter took a long rope of heavenly cotton, tied it to a tree, and threw it through the hole and lowered himself through the clouds to what is now Earth, forsaking his sky world.

The Warao have shamans, who perform music such as rain dances and songs.

The Warao have been considered to be the first inhabitants of Guyana, predating the arrival of Arawak and Caribs.
