Kauaʻi (Hawaiian: [kɐwˈwɐʔi]), anglicized as Kauai (English: /ˈk/ KOW-eye or /kɑːˈwɑː./ kah-WAH-ee), is one of the main Hawaiian Islands.

It has an area of 562.3 square miles (1,456.4 km2), making it the fourth-largest of the islands and the 21st-largest island in the United States. Kauaʻi lies 73 miles (117 km) northwest of Oʻahu, across the Kauaʻi Channel. The island's 2020 population was 73,298.

Styling itself the "Garden Isle", Kauaʻi is the site of Waimea Canyon State Park and Nā Pali Coast State Park. It forms the bulk of Kauaʻi County, which includes Niʻihau as well as the small nearby islands of Kaʻula and Lehua.
